Consists of the following:

1) Integers of different sizes

Type Size(bytes) Type Size

char 1 int 2 or 4

short 2 long 4 or 8

The above can be preceded by the key words signed or unsigned to specify signed or

unsigned integers, e.g.., signed char (defines integer from -127 to 128)

unsigned long (defines integers from 0 to (2^64-1)

2) Floating point numbers

type Size in bytes

float 4

double 8

long double 16

The integer and floating point types can be preceded by the key word const to specify

constants, e.g., const int Max=10; // constants must be initialized when declared.
