RANGE AND SIZE OF INTEGERS

QUES :-
Find the range and size of integer data type in your C compiler, through programming and verify using sizeof opereator.
ANS:-
/******************************************************************************/
#include<stdio.h>
#include<conio.h>

int main()
{
int *ptr,i=0;
long j;
clrscr();
ptr=0;
ptr++;
printf("Size of integer on your compiler is %d\n",ptr);
printf("Size of integer using sizeof operator = %d\n",sizeof(int));
while(i>=0)
j=i++;

printf("Range = %d to %ld",i,j);
getch();
return 1;
}
