Integer data Types

Integers are whole numbers with a wide range of values that are machine dependent. Integer occupies 2 bytes memory space and its value range limited to -32768 to +32767.  Integer data type allows a variable to store numeric values. “int” keyword is used to refer integer data type. The storage size of int data type is 2 or 4 or 8 byte. It varies depending upon the processor in the CPU that we use.  If we are using a 16-bit processor, 2 bytes (16 bit) of memory will be allocated for int data type.
