may be adding return 0; would be good in future. All the best.

    From Wikipedia:
    Within functions that define a non-void return type, failure to return a value before control reaches the end of the function results in undefined behaviour (compilers typically provide the means to issue a diagnostic in such a case).[17] The sole exception to this rule is the main function, which implicitly returns a value of zero.[18]

      Hm... Wikipedia... Is it a new compiler?

      A lot of contestants during last 15 years have a lot of trouble because of omission of this ending return. Surely one could enjoy spending his time during contest and found out how present compiler reacts.

      But I suppose that such experiments are not real goal for contestants.

      There are specific compilers + library suits which does not even allow main to have "int" type (like Keil or WinAVR), but that means nothing.

        Quote has a link to standard of language c++. It's a compiler's problem, if it doesn't follow standards.

          Compiler's problem would become contestant's problem if he want to rely upon some "standard" but obscure facts, without significant reason to do so. I believe that MSVC and G++ would work well, and none would use Borland. But I do not see what for we need to skip these few characters if it is altogether proper and meaningful that int function should return int value.

Adding \n at the end of the message would also be a better practice I think...
