In this video, I will give a brief overview of variables, keywords, and constants in the C programming language. I will talk about the difference between variables, constants and keywords in C

A variable in C is an entity whose value keeps on changing throughout the program execution.
Variables, constants, or keywords in C can be formed from any combination of Alphabets, Digits, and Special Symbols. A constant in C programming is an entity whose value does not change throughout the execution.

The value of variables in C may or may not change during the execution of the program.
The value of a constant in C will never change during program execution.
Keywords in C are the words reserved for the C compiler and can only be used for a special purpose.
