Pointer Addition: Adding integer value with Pointer

Adding integer value with Pointer

int *ptr , n;
ptr = &n ;
ptr = ptr + 3;

#include<stdio.h>

int main(){

int *ptr=(int *)1000;

ptr=ptr+3;
printf("New Value of ptr : %u",ptr);

return 0;
}

Output :

New Value of ptr : 1006

Formula :

ptr = ptr   + 3 * (sizeof(integer))
    = 1000  + 3 * (2)
    = 1000  + 6
    = 1006
