int main()
{
    int j;
    int i;
    int *p; // declare pointer

    i = 7;
    p = &i; // The pointer now holds the address of i
    j = *p;

    printf("i = %d \n", i);  // value of i
    printf("j = %d \n", j);  // value of j
    printf("*p = %d \n", p); // the address held by the pointer

    *p = 32; // asigns value to i via the pointer

    printf("i = %d \n", i);   // value of i
    printf("j = %d \n", j);   // value of j
    printf("*p = %d \n", p);  // the address held by the pointer
    printf("&i = %d \n", &i); // address of i
