Data types are means to identify the type of data and associated operations for handling it. Every variable in C has a data types.
Integers are used to store whole numbers.
In C programming, 4 Bytes memory is allocated for Integer datatype. Size and range of Integer type on 16-bit machine is given below:
| Type | Size(bytes) | Range |
|---|---|---|
| int or signed int | 2 | -32,768 to 32767 |
| unsigned int | 2 | 0 to 65535 |
| short int or signed short int | 1 | -128 to 127 |
| unsigned short int | 1 | 0 to 255 |
| long int or signed long int | 4 | -2,147,483,648 to 2,147,483,647 |
| unsigned long int | 4 | 0 to 4,294,967,295 |
