you can't really do that in the for loop. How about checking for true or false in the for loop and then write the statement outside.

Code:

---

bool fib = false;
for(int j=0;j<18;j++)
{
  if(a[j]==no )
    {
      fib = true;
      break;   
    }
}
if ( fib == true)
  std::cout << no << " is a fib" << std::endl;
else
  std::cout << no << " is not a fib << std::endl;

Did you see this popup when you submitted your code?

If you did, what did you do about it?
