Confused with Result

[rachelle]

I have my C program as below:

void main()
{
int *s,*t;
s=(int*)2000;
t=(int*)3000;
printf("%d",(t-s));
}

I thought the output would be 1000. But the output was 500.I was confused with why I got this output. Someone explain me on this.

t and s are pointer variables not int and they hold memory address
try using

printf("%d",(*t-*s)); instead of printf("%d",(t-s));

The result 500 is perfectly right. This is because t and s are declared as integer pointer variable and integer variables occupy 2 bytes generally and so the difference of 1000 space is equal to 500 integer spaces apart. This is the reason for getting output as 500.

because size of integer is 2 bytes.
the statement subtracts 3000-2000 in steps of 2 .
hence the answer is 2
