}


int main(){
	
	while (menu()) {
		while (story());
		while (game());
		clear();
	}

	return 0;
}


any idea why? :\

I would not call this simple, overly complex would be a better description. Without getting into any of that, it does guess the right number on the second try every time, if you enter an even number. The reason for that is order of precedence.

guess = minimum + maximum / 2;

Even if you fix that, however; it will never guess an odd number because of integer division.
