C data types are defined as the data storage format that a variable can store a data to perform a specific operation. Data types are used to define a variable before to use in a program. Size of variable, constant and array are determined by data types.

What is range of data type?

Range means the maximum and minimum value that can be stored inside the variable of a given type. For example if you have unsigned char and if we assume that the size of the datatype is 8 bits then you can store values ranging from 0 – 2^8-1 i.e. 0-255 inside it.
