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.

Difference between variable and constant in terms of memory types?
constant means data item whose value cannot be altered or change. whereas variable is named storage location whose value can be manipulated during program run.
What is the difference between the structure tag and structure variable?
The structure tag is a type. The structure variable is an instance of that type.
What is constant explain their storage representation with suitable example?
A constant is a variable that is immutable. The storage representation is exactly the same as for any other variable of the same type, the only difference is that all constants are allocated in the program's data segment (static memory).
What is the difference between a constant and a variable in java programming language?
A constant in Java is defined using the "final" modifier. For instance: final double Density_Of_Water = 1.000; would set Density_Of_Water to 1.000. This value can not be modified throughout the program because "final" told the compiler that this value would not change. A variable however, can be changed by the user throughout the program.
