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:
|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|
