Getting wrong output in C program [closed]

Question

Expected output : "total is equal to 114"

Current output : "total is equal to -334"

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>

#define SZ 3

int main(void) {
    int i, one = 0, two = 0, total = 0;

    printf(
        "Enter two whole numbers separated by a space: ");  // user enters 56 2

    total = scanf("%d %d", &two, &one);

    for (i = 0; i < SZ; i++) {
        if (i / two) {
            total = two + one / total;           
        } else {
            total -= one * two;           
        }
    }

    printf("total is equal to %d\n", total);

    return 0;
}

Answer 1

if(i / two) is always false:

• 1st iteration -> 0 / 56 = 0
• 2nd iteration -> 1 / 56 = 0.02 which is treatead as int, so 0
• 3rd iteration -> 2 / 56 = 0.04 same as before

Given the above, and knowing that 0 is false, only the else block is executed 3 times, since scanf returns the number of read inputs, which is 2, and you assign it to total, total begins with the value 2, so:

2 -= 56 * 2 is -110

-110 -= 56 * 2 is -222

-222 -= 56 * 2 is -334

And that's how you get that value.

As for the 114 value you want, it's not clear how or for what reason or logic it should be achieved.
