Write a program to implement subtraction of a number to a pointer.

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int num1,num2;    
    int *ptr1,*ptr2;   
    int sub;            
    printf("Please enter value for num1: "); 
    scanf("%d",&num1);                 
    printf("Please enter value for num2: "); 
    scanf("%d",&num2);
    ptr1=&num1;
    ptr2=&num2;
    sub=*ptr1 - *ptr2;
    printf("Subtraction of the two integer values is: %d",sub);
    return 0;
}

Output

Please enter value for num1: 90
Please enter value for num2: 89
Subtraction of the two integer values is: 1
