## How to find range of data types in C programming?

In C programming data types play a major role, so is their size and range. The `sizeof()`

operator gives you bytes required to store value of some type in memory. However, in programming you must be aware of range of a type to avoid overflow and underflow errors.

The size of a data type is compiler dependent and so is its range. So, you must not hardcode size and range values in your program.

There are two ways to find minimum and maximum range of a type. You can use any of the approach to get range of a type.
