Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main()
{
    int a,b;
    scanf("%d%d",&a,&b);
    
   if (a+b>a-b)
   {printf("The largest among them is %d\n",a+b);}
  else if(a-b>a+b)
     {printf(" The largest among them is%d\n",a-b);}
else  if(a+b>a*b)
 {printf(" The largest among them is%d\n",a-b);}
 else if(a-b>a*b)
   {printf(" The largest among them is%d\n",a-b);}
   else
   {
         {printf(" The largest among them is%d\n",a*b);}
   }

    return 0;
