C Program for Smallest of three numbers without comparing

There are many ways to find smallest. Below program will accept 3 integer numbers from user

We are using while loop here and one increment variable.

Every time program is subtracting value by 1 and incrementing counter variable by 1. once condition is false program will return smallest number. This is simple basic mathematical operation. Below is complete running code.

// Program Name: C Program to find smallest number without comparison
#include <stdio.h>

void main()
{
    int num1,num2,num3;
    int counter=0;
    printf("\n\tEnter first Integer Number\t");
    scanf("%d",&num1);
    printf("\n\tEnter Second Integer Number\t");
    scanf("%d",&num2);
    printf("\n\tEnter Third Integer Number\t");
    scanf("%d",&num3);
    
    
    // Here we are using while loop when result is false we will get smallest number 
    while(num1 && num2 && num3)
    {
        num1--;
        num2--;
        num3--;
        counter++;
    }
    printf("\n\t Minimum of 3 Number is %d", counter);
}

Output

Enter first Integer Number      4

        Enter Second Integer Number     3

        Enter Third Integer Number      0

         Minimum of 3 Number is 0
