Add two numbers using pointers with C.

 // Perform arithmetic operation  //

    sum  = (*ptr1) + (*ptr2);

    diff = (*ptr1) - (*ptr2);

    mult = (*ptr1) * (*ptr2);

    div  = (*ptr1) / (*ptr2);


#include <stdio.h>

int main()
{
    int num1, num2, sum;
    int *ptr1, *ptr2;

    ptr1 = &num1; // ptr1 stores the address of num1
    ptr2 = &num2; // ptr2 stores the address of num2

    printf("Enter any two numbers: ");
    scanf("%d%d", ptr1, ptr2);

    sum = *ptr1 + *ptr2;

    printf("Sum = %d", sum);

    return 0;
}


Output

Enter any two numbers : 5 10
Sum = 15
