THE FOLLOWING MUST BE CODED IN C   THE FOLLOWING MUST BE CODED IN C

Write a program that demonstrates handling pointers. Create two integer variables m and n, and two pointers, pm pointing to m, and pn pointing to n.

Produce the following output:

Address of m: 0x7ffcc3ad291c

Value of m: 29

Address of n: 0x7ffcc3ad291d

Value of n: 34

Now pm is pointed to m by assigning the address of m to pm

Address of pointer pm: 0x7ffcc3ad2100

Value of pointer pm: 0x7ffcc3ad291c

Content of pointer pm (dereferencing): 29

Now pn is pointed to n by assigning the address of n to pn

Address of pointer pn: 0x7ffcc3ad2101

Value of pointer pn: 0x7ffcc3ad291d

Content of pointer pn (dereferencing): 34

Thank you!

Answer 1

#include <stdio.h>
int main()
{
int m=29,n=34;
int* pm, *pn;
  
  

printf("Address of m: %p\n", &m);
printf("Value of m: %d\n", m);
printf("Address of n: %p\n", &n);
printf("Value of n: %d\n", n);

pm=&m;
pn=&n;

printf("Address of pointer pm: %p\n", &pm);
printf("Value of pointer pm: %p\n", pm);
printf("Content of pointer pm(dereferencing): %d\n",*pm);
  
printf("Address of pointer pn: %p\n", &pn);
printf("Value of pointer pn: %p\n", pn);
printf("Content of pointer pn(dereferencing): %d\n",*pn);
  

return 0;
