Logic To Find Biggest of 3 Numbers using Binary Minus Operator

If user enters a = 1, b = 2, c = 3;

We check if a – b > 0 and a – c > 0
i.e., 1 – 2 > 0 and 1 – 3 > 0
=> -1 > 0 and -2 > 0 (Both these conditions are false).
So a is not the biggest.

In else block we check if b – c > 0
=> 2 – 3 > 0
=> -1 > 0 (which is false)
So b is not the biggest.

In that case whatever number present in variable c is biggest.

Source Code: C Program To Find Biggest of 3 Numbers using Binary Minus Operator

#include < stdio.h >

int main()
{
    int a, b, c;

    printf("Enter 3 numbers\n");
    scanf("%d%d%d", &a, &b, &c);

    if(a-b > 0 && a-c > 0)
    {
        printf("%d is the biggest\n", a);
    }
    else
    {
        if(b-c > 0)
        {
            printf("%d is the biggest\n", b);
        }
        else
        {
            printf("%d is the biggest\n", c);
        }
    }

    return 0;
}

Output 1:
Enter 3 numbers
1
2
3
3 is the biggest

Output 2:
Enter 3 numbers
10
30
20
30 is the biggest

Output 3:
Enter 3 numbers
100
50
75
100 is the biggest
