signed integers : which contains both the +ve and -ve numbers
. The format specifier for signed integers is %d or we can
use %i also.
the range is same as the int.

Unsigned integers:
the range of unsigned integer is 0to65535.
the format specifier for this is %u.
generally this is used to print the address of a variable.
unsigned integer doesnt contain negative value.
eg:
main()
{
int i;
printf("enter i value");
scanf("%d",&i);
printf("the value stored in the i variable is%d",i);
printf("address is %u",&i);
getch();
}
