'X' isn't a defined variable in AskQuestion. You can, however, use the '*' operator. Here is an example:

void AskQuestion(/* not using anything here */) {
int one, two, answer;
srand(time(0));
one = rand()%500 + 1;
two = rand()%500 + 1;
std::cout << "What is " << one << " * " << two << std::endl;
std::cin >> answer;
if (answer == one * two)
std::cout << "Correct!" << std::endl;
else
std::cout << "Wrong..." << std::endl;
}

But when i want to enter the function i want to do this :
void AskQuestion(/); or
void AskQuestion(+);
You could use a
char to store the character, and switch based on it. Here is an example:

void AskQuestion(char op) {
int one, two, answer;
bool isCorrect = false;
one = rand() % 500 + 1;
two = rand() % 500 + 1;
std::cout << "What is " << one << " " << op << " " << two << "? ";
std::cin >> answer;
switch (op) {
case '+':
if (answer == one + two) isCorrect = true;
break;
case '-':
if (answer == one - two) isCorrect = true;
break;
case '*':
if (answer == one * two) isCorrect = true;
break;
case '/':
if (answer == one / two) isCorrect = true;
break;
}
if (isCorrect)
std::cout << "Correct!" << std::endl;
else
std::cout << "Wrong..." << std::endl;
}
int main() {
srand(time(0));
AskQuestion('+');
AskQuestion('*');
AskQuestion('-');
return 0;
}
