Question

1. declare two integer variables x and y and two pointers to p and q. initialize the value of x with 2, y with 8 and the pointer p should point to the address of x and q should point to the address of y. 2. then write a C statements that will print the following information:

a. the address of x and the value of y.

b. the value of p and the value of *p.

c. the address of y and the value of y.

d. the value of q and the value of *q.

e. the address of p (not its contents).

f. the address of q ( not its contents).

Answer 1

#include<stdio.h>
int main()
{
   //declaring varibles
   int x,y;
   int *p,*q;
  
   x=2;
   y=8;
   p=&x;//p points to the address of x
   q=&y;//q points to the address of y.
  
  
   //a
   printf("address of x :%u\nvalue of y:%d\n",&x,y);
   //b
   printf("value of p :%u\nvalue of *p:%d\n",p,*p);
   //c
   printf("address of y :%u\nvalue of y:%d\n",&y,y);
   //d
   printf("value of q :%u\nvalue of *q:%d\n",q,*q);
   //e
   printf("address of p:%u\n",&p);
   //f
   printf("address of q:%u\n",&q);
  
   return 0;
}

output:

address of x :6487644
value of y:8
value of p :6487644
value of *p:2
address of y :6487640
value of y:8
value of q :6487640
value of *q:8
address of p:6487632
address of q:6487624
