Detailed explanation-1: -A constant is a data item whose value cannot change during the program’s execution. Thus, as its name implies – the value is constant. A variable is a data item whose value can change during the program’s execution. Thus, as its name implies – the value can vary.
Detailed explanation-2: -What is the Difference between Constant and Variables? A constant does not change its value over time. A variable, on the other hand, changes its value dependent on the equation. Constants are usually written in numbers.
Detailed explanation-3: -A variable is a value that changes or has the possibility to change. A constant is a value that does not vary over time.
Detailed explanation-4: -Difference between Variables and Constant in C Program The value of a variable can change depending on the conditions. In constants, the value cannot be changed. Typically, it uses int, float, char, string, double, etc. data types in a program.
Detailed explanation-5: -Variables and constants offer various ways to represent and manipulate data. Constants, as the name suggests, have fixed values. Variables, on the other hand, hold values which can be assigned and changed as the program executes.
