I think the "Best answer" deserves to be correct: there's a

return 0;

missing from the end of the main().

Answer 2

#include <stdio.h>

int main()
{
   int num=0;
   for(int i=4;i>0;i--)
   {
       for(int j=0;j<i;j++)
       {
           printf("%d",num);
       }
        printf("\n");
        num++;
   }

    return 0;
}
