Computer Science SSC II Notes - AKUEB

8.4.1 Differentiate between a constant and a variable in C programming language;

  Constant:

             Constants are fixed values that do not change during the execution of a program. They are also referred to as literals. Constants can be of different types, such as integer constants, floating-point constants, character constants, and string literals. Constants provide a way to represent fixed values that remain the same throughout the program. For example:

  int x=6; // the value of x is constant [6]

 

Variable:

             Variables are used to store and manipulate data that can change during the execution of a program. They provide a way to represent dynamic or varying values. Variables have a specific type, which determines the kind of data they can store, such as integers, floating-point numbers, characters, or custom-defined data types. For example:

  int x; // x is a variable of integer format [Its value can change]
