Build a program that allows a user to select one of the following four menu options: enter new integer value, print pointer address, print integer address, and print integer value. For this program you will need to create two variables: one integer data type and one pointer. Using indirection, assign any new integer value entered by the user through an appropriate pointer.

I need help to fix my code:

#include<stdio.h>

main()

{

int d=0, *dPtr;

char c; 

dPtr=&d;

printf(“Menu Options:n”);

printf(“a. a new integer value.n”);

printf(“b. a pointer address.n”);

printf(“c. the address of an integer.n”);

printf(“d. the value of an integer.n”);

scanf(“%c”, &c);

switch(c){

case ‘a’:

printf(“Enter an integer:”);

scanf(“%d”, &d);

break;

case ‘b’:

printf(“%p”, dPtr);

break;

case ‘c’:

printf(“%p”, &d);

break;

case ‘d’:

printf(“%dn”, d);

break;

}

}
