Solution in C (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int x,y,he,cha,ji,max;
    scanf("%d %d",&x,&y);
    he=x+y;
    cha=x-y;
    ji=x*y;
    if(he>cha)
    {
        max=ji>he?ji:he;
    }
    else
    {
        max=ji>cha?ji:cha;
    }
    printf("%d+%d=%d, %d-%d=%d and %d×%d=%d. The largest among them is %d.",x,y,he,x,y,cha,x,y,ji,max);
    return 0;
