SQL is considered difficult to learn; its command set has a vocabulary of more than 300 words.
a. True
b. False
Answer:
Explanation:
a. True
SQL (Structured Query Language) is a programming language used to manage data in relational databases. While it is relatively easy to learn the basic concepts of SQL, it can become more challenging as you learn the more advanced concepts and try to write more complex queries.
The command set for SQL does have a relatively large vocabulary, with over 300 words and commands that can be used to perform various tasks such as creating and modifying tables, inserting, updating and retrieving data from a database. It also can have slight variations depending on the specific implementation of SQL such as ANSI SQL, MySQL SQL, PostgreSQL SQL.
It's not necessarily difficult to learn, but it does take time and practice to become proficient in it. There are many resources available online that can help you learn SQL, such as tutorials, videos, and documentation, and many SQL tutorials are available for free. You can also practice by creating your own small databases and experimenting with different queries.
TRUE OR FALSE : with pointer variables you can access, but you cannot modify, data in other variables.
True, with pointer variables you can access, but you cannot modify, data in other variables.
Which regarding a pointer variable is true?
A pointer variable, also referred to as a pointer or just a pointer, functions similarly to other variables that can hold data. A pointer saves a memory address instead of a value like a conventional variable would (such as an int, double, or char). Similar to a regular variable, pointers must be declared before they may be utilized.
Why not use variables instead of pointers?
In essence, a pointer can be used to point to any variable of the same type (e.g. any integer, double, char, etc.).
The values of numerous distinct variables of the same type can be updated or changed using this method. Using pointers speeds up execution as well. More quickly can be accessed memory.
