I tried to do this:

#include <stdio.h >

int main(void) {

    int common = 0;
    int num1;
    int num2;
    int big;
    int small;
    int i; 
    printf("Enter the first number  : ");
    scanf("%d", &num1);

    printf("Enter the second  number  : ");
    scanf("%d", &num2);

    if (num1 <= num2) {
        num1 = small;
        num2 = big;
    }
    else{
        num1 = big;
        num2 = small; 
    }
    for  (i = small ; ; i  )
    {

    }

I don't know what is meant by to 1 do. I'm beginner in algorithms
but I think it means i isn't?

CodePudding user response：

The algorithm says to count from small down to 1. So the repetition should be i--, not i . Use i >= 1 as the repetition condition to keep looping until you get to 1.

for (i = small; i >= 1; i--)
