The constants in C are the read-only variables whose values cannot be modified once they are declared in the C program. The type of constant can be an integer constant, a floating pointer constant, a string constant, or a character constant. In C language, the const keyword is used to define the constants.
In this article, we will discuss about the constants in C programming, ways to define constants in C, types of constants in C, their properties and the difference between literals and constants.
Types of Constants in C
The type of the constant is the same as the data type of the variables. Following is the list of the types of constants
- Integer Constant
- Character Constant
- Floating Point Constant
- Double Precision Floating Point Constant
- Array Constant
- Structure Constant
