Answer:
from datetime import time, datetime, timedelta, date
for _ in iter(list, 0):
t1 = input("Please enter time one: ")
t2 = input("Please enter time two: ")
if t1.isdigit() == True and (int(t1[:2])<=23 and int(t1[2:]) <= 59)\
and t2.isdigit() == True and (int(t2[:2])<= 23 and int(t2[2:])<=59):
time_1 = time(hour=int(t1[:2]), minute=int(t1[2:]))
time_2 = time(hour= int(t2[:2]), minute=int(t2[2:]))
if time_1 > time_2:
diff = datetime. combine (date. today( ), time_1) - datetime. combine(date. today ( ), time_2)
else:
diff = datetime. combine (date. today( ), time_2) -datetime. combine(date. today ( ), time_1)
diff_list = str(diff).split(":")
del diff_list[2]
diff_t = "". join (diff_list)
print(diff_t)
break
if t1.isdigit() == False or t2.isdigit() == False:
print("Military Time Forest Required: Bad input, try again.")
continue
elif int(t1[:2])> 23 or int(t2[:2])> 23:
print("Military Tine Format Required: Hours must be between 00 and 23, try again")
continue
elif int(t1[2:])> 59 or int(t2[2:])> 59:
print("Military Tine Format Required: Minutes must be between me and 59, try again")
continue
Explanation:
The python Datetime package is used to manipulate date and time, creating immutable Datetime objects from the various python data types like integer and string. The block of code above is a conditional for-loop statement that gets two user time value inputs and prints out the difference as a string in Military forest time format.

You are given a 5-letter word (for example, abcde). Write a C-Program which outputs all possible unique 5 letter permutations of this word in a text file. There should be no repetition of letters in permutation (i.e. in our example, bacde is a valid permutation but bbcde is invalid. Use of library functions for generation of permutations is NOT allowed.
The text file containing the output should be named as q3out.txt. Each word of the output must be on a separate line in the text file. The 5-letter input word should be read by your program from the console. Provide comments in your code. Submit your C code, and the q3out.txt file for the following inputs:
(a) parba
(b) arbca
Answer:
See attachment 1 for code
See attachment 2 for the output of permuting letters of parba
See attachment 3 for the output of permuting letters of arbca
Explanation:
The program was implemented in C
The program uses a recursive function letterpermutation and a swap function to successfully implement the requirement of this question.
The letterpermutation function is defined here
void letterpermutation(char *mystring, int index1, int index2) {
This lets the program writes to a file
FILE *fptr;
This opens the file in an appending mode
fptr = fopen("q3out.txt","a");
int i;
This checks for unique strings.
if (index1 == index2) {
If found, this appends the string to the text file
fprintf(fptr,"%s\n",mystring); }
If otherwise
else{
This iterates through the string
for (i = index1; i <= index2; i++) {
The swap function is called to swap the characters of the string
swap((mystring+index1), (mystring+i));
This calls the function, recursively
letterpermutation(mystring, index1+1, index2);
This further swaps the characters of the string
swap((mystring+index1), (mystring+i));
} } }
The swap function begins here and what it literally does is that it swaps characters of the input string to create a new string
void swap(char *ch1, char *ch2) {
char temp;
temp = *ch1; *ch1 = *ch2; *ch2 = temp; }
The main function begins here
int main() {
This declares and initializes the string
char mystring[] = "ABCd"; // The string here can be changed
This calls the function to permute the string
letterpermutation(mystring, 0, strlen(mystring)-1);
return 0; }

The IBM system/370 architecture uses a two-level memory structure and refers to the two levels as segments and pages, although the segmentation approach lacks many of the features described in Chapter 8. For the basic 370 architecture, the page size may be either 2 KB or 4 KB, and the segment size is fixed at either 64 KB or 1 MB. For the 370/XA and 370/ESA architectures, the page size is 4 KB and the segment size is 1 MB. What advantages of segmentation does this scheme lack
Answer:
Explanation:
Introductory thought:
Thinking about the architecture for the IBM System/370 that is fit for giving higher preparing force and more stockpiling limit since it utilizes two-level of memory structure which is known as the segments and caches and the given plan is as per the following:
In division the address space is isolated into quantities of segments of variable sizes and then again in paging the address space is partitioned into quantities of fixed-sized units that are known as pages.It is more helpful for better utilization of memory. The fundamental architecture for the IBM system/370 architecture the size of the page are for the most part either 2KiloBytes (KB) or 4KB and the size of the segments will be changed from 64KiloBytes to 1MegaBytes. The two dissimilar kinds of architecture that existed are 370/XA that is the Extended Architecture, also the other is 370/ESA known as the Enterprise Systems Architecture. The page size is 4KB for the Extended variant and 1MB for the Enterprise Systems Architecture (ESA).Advantages of segmentation that the given scheme needs to incorporate includes:
In the configuration of the architecture for IBM System/370 the segments are of a fixed size which isn't noticeable for the programmer and as such he will know the interior subtleties and subsequently inside architecture is stowed away from outside gentle. In IBM system/370 the reference bit is zero for the processor hardware as well as at whatever point another page is stacked into the edge, the reference bit is changed to one after referring to a specific area inside the casing. The quantity of lines of the page outline table is overseen by the Operating System and a page outline table section is moved to start with one line then onto the next depending on the length of the span of the referenced bit from the page outline which is sets to nothing. Whenever there is a need to supplant the page then the page browsed the line of the longest life non referenced edges.
Write a program named Twitter that accepts a user’s message and determines whether it is short enough for a social networking service that does not accept messages of more than 140 characters.
If the message is more than 140 characters, output The message is too long. Otherwise output The message is okay.
Explanation:
It's a very easy one, Liev:
using System;
class Twitter
{
static void Main()
{
Console.WriteLine("Enter your message");
Console.WriteLine();
string message = Console.ReadLine();
Console.WriteLine();
if (message.Length <= 140)

Write a SELECT statement that returns these four columns from the Products table: The list_price column A column that uses the FORMAT function to return the list_price column with 1 digit to the right of the decimal point A column that uses the CONVERT function to return the list_price column as an integer A column that uses the CAST function to return the list_price column as an integer Use column aliases for all columns that contain a function.
Answer:
See explanation below
Explanation:
SELECT list_price,
FORMAT(list_price, 1) AS formatted_list_price,
CONVERT(INT, list_price) AS converted_list_price,
CAST (list_price AS INT) AS casted_list_price
FROM products_table;
In SQL, the SELECT statement is used to initiate a query. It lists the variables that will be contained in the output, just like choosing items on a list, with each item being separated by a comma.
The FORMAT, CONVERT, CAST are all functions that are used to change the format of a value. Their formats are;
FORMAT - Format (value, decimal places)CONVERT - Convert (datatype, value)CAST - Cast ( value AS datatypeIn SQL, aliases are used to rename variables (usually those that contain functions) to ones taste. The AS is used after the function and the new name follows right after.

Implement a class named Rectangle. The class should contain:
1. Two data attributes of type float named width and height that specify the width and the height of the rectangle.
2. A constructor that creates a rectangle with the specified width and height. If no argument is provided, it should use 1.0 for both values. If any input value is negative, the function should raise an exception.
3. Functions get_width and get_height that return the corresponding value
4. The set_width and set_height function that update the values if and only if the input is positive; otherwise do nothing
5. Functions get_area and get_perimeter that return the area and the perimeter of this rectangle respectively.
6. A function rotate that swaps the height and width of a rectangle object.
7. A class variable count that keeps track of the number of rectangles created so far.
8. A class method get_count that returns the above value.
9. An equality operator that returns True if and only if the two rectangles are of the same shape.

Write a for loop that computes the sum the first 10 positive integers. For each loop, you should use two variables. One that runs through the first 10 positive integers, and one that stores the result of the computation. To test your code, what is the sum of the first 10 positive integers
Answer:
public class Main{
public static void main(String[] args) {
//The While Loop
int i = 1;
int sum = 0;
while(i <=10){
sum+=i;
i++; }
System.out.println("Sum: "+sum);
//The for Loop
int summ = 0;
for(int j = 1;j<=10;j++){
summ+=j; }
System.out.println("Sum: "+summ); } }
Explanation:
The while loop begins here
//The While Loop
This initializes the count variable i to 1
int i = 1;
This initializes sum to 0
int sum = 0;
This while iteration is repeated until the count variable i reaches 10
while(i <=10){
This calculates the sum
sum+=i;
This increments the count variable i by 1
i++; }
This prints the calculated sum
System.out.println("Sum: "+sum);
The for loop begins here
//The for Loop
This initializes sum to 0
int summ = 0;
This iterates 1 through 10
for(int j = 1;j<=10;j++){
This calculates the sum
summ+=j; }
This prints the calculated sum
System.out.println("Sum: "+summ); }

If x2 - y2 = 1, then
dx
1
(a) yx-1
(C) xy-1
(b) -xy-
(d) - yx
Answer:
xy-1
Explanation:
Given expression is :
[tex]x^2-y^2=1[/tex] ..(1)
We need to find the value of [tex]\dfrac{dy}{dx}[/tex].
Differentiating equation (1) wrt x.
[tex]\dfrac{d}{dx}(x^2-y^2)=1\\\\2x-2y\times \dfrac{dy}{dx}=0\\\\2y\times \dfrac{dy}{dx}=2x\\\\y\times \dfrac{dy}{dx}=x\\\\\dfrac{dy}{dx}=\dfrac{x}{y}[/tex]
or
[tex]\dfrac{dy}{dx}=xy^{-1}[/tex]
Hence, the correct option is (c) "xy-1".
Explain how data is represent in the computer system
Explanation:
Computers use binary - the digits 0 and 1 - to store data. A binary digit, or bit, is the smallest unit of data in computing. It is represented by a 0 or a 1. Binary numbers are made up of binary digits (bits), eg the binary number 1001.Develop a C program that calculates the final score and the average score for a student from his/her (1)class participation, (2) test, (3) assignment, (4) exam, and (5) practice scores. The program should use variables, cout, cin, getline(), type casting, and output manipulators. The user should enter the name of the student and scores ranging from 0 to 100 (integer) for each grading item. The final score is the sum of all grading items. The average score is the average of all grading items.
Answer:
#include <iomanip>
#include<iostream>
using namespace std;
int main(){
char name[100];
float classp, test, assgn, exam, prctscore,ave;
cout<<"Student Name: ";
cin.getline(name,100);
cout<<"Class Participation: "; cin>>classp;
while(classp <0 || classp > 100){ cout<<"Class Participation: "; cin>>classp; }
cout<<"Test: "; cin>>test;
while(test <0 || test > 100){ cout<<"Test: "; cin>>test; }
cout<<"Assignment: "; cin>>assgn;
while(assgn <0 || assgn > 100){ cout<<"Assignment: "; cin>>assgn; }
cout<<"Examination: "; cin>>exam;
while(exam <0 || exam > 100){ cout<<"Examination: "; cin>>exam; }
cout<<"Practice Score: "; cin>>prctscore;
while(prctscore <0 || prctscore > 100){ cout<<"Practice Score: "; cin>>prctscore; }
ave = (int)(classp + test + assgn + exam + prctscore)/5;
cout <<setprecision(1)<<fixed<<"The average score is "<<ave;
return 0;}
Explanation:
The required parameters such as cin, cout, etc. implies that the program is to be written in C++ (not C).
So, I answered the program using C++.
Line by line explanation is as follows;
This declares name as character of maximum size of 100 characters
char name[100];
This declares the grading items as float
float classp, test, assgn, exam, prctscore,ave;
This prompts the user for student name
cout<<"Student Name: ";
This gets the student name using getline
cin.getline(name,100);
This prompts the user for class participation. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Class Participation: "; cin>>classp;
while(classp <0 || classp > 100){ cout<<"Class Participation: "; cin>>classp; }
This prompts the user for test. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Test: "; cin>>test;
while(test <0 || test > 100){ cout<<"Test: "; cin>>test; }
This prompts the user for assignment. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Assignment: "; cin>>assgn;
while(assgn <0 || assgn > 100){ cout<<"Assignment: "; cin>>assgn; }
This prompts the user for examination. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Examination: "; cin>>exam;
while(exam <0 || exam > 100){ cout<<"Examination: "; cin>>exam; }
This prompts the user for practice score. The corresponding while loop ensures that the score s between 0 and 100 (inclusive)
cout<<"Practice Score: "; cin>>prctscore;
while(prctscore <0 || prctscore > 100){ cout<<"Practice Score: "; cin>>prctscore; }
This calculates the average of the grading items
ave = (int)(classp + test + assgn + exam + prctscore)/5;
This prints the calculated average
cout <<setprecision(1)<<fixed<<"The average score is "<<ave;

state and explain application areas where computer are applied
Answer:
There are at least five areas that are covered by computer applications, and five of those are business, government, military, manufacturing, and music. There are also other areas such as scientific and the role of technology in our society is growing annually.
Computers have now for several decades brought automation to the table in small, medium, and large businesses. There are word processing and spreadsheet applications for small businesses all the way up to enterprise-wide applications that cover every aspect of a large business such as accounting, inventory, shop floor, management, and feature real-time reporting capability that can give a snapshot glimpse of the financial position of a company at any point in time.
The government has a wide variety of computer applications. Government uses many of the same tools as small to large businesses in desktop type applications and many that are much more advanced that are used in the military. Manufacturing applications involve computer-aided design and applications that are used to track production from the time a raw material is moved into the warehouse all the way to the production floor and back into the warehouse as a finished good.
Military only applications include systems that use GPS in missiles to hone in on targets from miles away. There are all kinds of other applications some of which are secret in nature and the public does not become aware of these until a war is underway. Computer applications in music can help to transcribe and compose music as well as provide accompaniment for a musician to practice with.
Expect the number of computer applications in all of these fields to become more common in the future. Expect many applications to take the place of people to save money in a cash-crunched economy where everyone is looking for more ways to save money and cut costs.
