Why we cannot use keywords as a variable

Asked By becci99 0 points N/A Posted on - 07/21/2011

HELLO!

I have a question in my mind; can anybody please help me? When we design code, if we use KEYWORDS as a variable for our own use in code an ERROR is usually displayed that "IT IS A RESERVED WORD". Why can't we use a keyword as a variable? Please explain any solid reason behind it.

Why we cannot use keywords as a variable

Hello,

• Reserve words have special meaning within the programming languages. They are special words use to identify the data types in language that supports the system, which identify the blocks and loops. They are also called keywords.
• So, when you use reserve keyword as a variable the compiler gets confused and treats that variable as a keyword. Their function is already defined in the system library, and the compiler behaves as though it is in the library. So, due to this reason, reserve words are not used as variables as this would create a problem to both the user (as goes through the program he can get confused) and also to the compiler.

Regards,

Charles.

Why we cannot use keywords as a variable

Hi Good Day,

The reason we cannot use it to declare a variable from the C programming is because the keywords are defined in the C language for specific purposes. If we declare a variable with the same name, the compiler would not know if you are trying to use a variable or that you are trying to perform an action with that keyword. That keyword cannot be used as a variable name.

Hope this will help to solve your problem.
