How to Subtract two numbers using pointers

In this c program, we are asking users to input two numbers and store them into pointer variables and using pointer variables to subtract two numbers using pointe.

#include <stdio.h>

int main()
{
// Declare 2 numbers
    int num1, num2;
    int	Sub;
// Declare 2 integer pointers
    int *ptr1, *ptr2;
	
// Assign numbers address to pointers
    ptr1 = &num1; 
    ptr2 = &num2; 

    printf("Please enter two numbers for Substraction: ");
    scanf("%d%d", ptr1, ptr2);

    Sub = *ptr1 - *ptr2;

    printf("The Substraction results are = %d", Sub);

    return 0;
}

Output

Please enter two numbers for Substraction: 5
10
The Substraction results are = -5
