FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Constants in c are the fixed values that are used in a program, and its value remains the same during the entire execution of the program. Constants are also called literals.

Detailed explanation-2: -Constant is an entity that refers to a fixed value of data and which cannot be modified. During execution/computation of programming, the value of a constant cannot be altered, it remains constant. PI = 3.1415927 whose value is universal and does not change.

Detailed explanation-3: -A constant is a fixed value. A constant is a number on its own, or sometimes a letter such as a, b, or c will represent a fixed number. For example, in the equation, x + 5 = 9, 5 and 9 are constants.

Detailed explanation-4: -Constants refer to fixed values that the program may not alter during its execution. These fixed values are also called literals. Constants can be of any of the basic data types like an integer constant, a floating constant, a character constant, or a string literal.

Detailed explanation-5: -A constant is a value that cannot be altered by the program during normal execution, i.e., the value is constant.
