A constant and variable are variations of data types.

int a;

is a variable and its value can be changed by the program as the program runs.

const int b;

is a constant with a fixed value and will have its value set and may not be changed by the program as as the program runs.

All data types may be declared as a constant.

Variable Value Can Be Changed By You In Programme.

A constant is a symbol that cannot be modified by the program while it is running, while a variable is a symbol that can be modified by the program while it is running. Constants are usually optimized as inline values, while variables will be stored on the stack or the heap.

What is the difference between a coefficient and variable?

A variable is a part of a term which can change. A coefficient is a numerical constant, associated with a variable. For example, in the term 3x^2 , 3 is the coefficient, while x is a variable.


What is the difference between constant speed and variable speed?

Constant speed refers to a consistent rate of motion without fluctuations, while variable speed involves changing rates of motion over time. In constant speed, the object moves at a steady pace throughout, whereas in variable speed, the object may accelerate or decelerate at different points.
