Answer 1

No error for me...

Answer 2

as @Valentin, it is compiling normally.
no error in the code.

Answer 3

Oh okay. So your function might not reach a return if you enter the same number for every input. If you add one last 'else', it should fix your problem. Like this:

// ......
else
if(d>a && d>b && d>c)

{return d;} }
else { /* new code is here*/
return -1;
}

Answer 4

There could be a problem, just for functionality, if the largest number is entered twice. It compiles fine for me though.

Answer 5
