Data types:

The variables use data-type during their declaration.

The data-type is used to determine the size of memory allocated. Here, the compiler allots the memory.

All data-type needs different sizes of memory.

Integer data type:

It is a number and it cannot have a fractional part. It may be a positive value, a negative value or zero.

Integer data type uses 4 bytes of memory...
