Do you know what overloading is? If so, this is a very simple task.

I know overloading is..
but...if 2 variables are typed in by user, how do I declare that two variables before cin?

You'll have to decide what you want the user to input (e.g. two ints, a char and an int, etc).

Hi, Jack_Chen -

This looks like a homework assignment. We'd be happy to help ... but you've got to take the first step.

Please write some code and post it. It doesn't have to be "correct" - just make an intelligent guess. Nylex is right - the answer is really, really simple.

But you need to post some code before we can help you any further.

OK?

PS:
Please be sure to use "code tags".

ha. I was overthinking...
The question just asked as I posted first time..
And I thought that require user to typein two variable.
But I am curiously want to know how to do so if user can typein any inputs..
Here's my code:

#include <iostream>
using namespace std;

void func(int x, int y) {
cout << " x + y = " << x+y;
}
void func(int x, char y) {
cout << "x = " << x << "\ty = " << y;
}
void func(char x, char y) {
cout << "x = " << x << "\ty = " << y;
}

int main() {
string x, y;//I don't know how to declare on here.
cout << "enter first var: ";
cin >> x;
cout << "and second: ";
cin >> y;
func(x, y);

system("PAUSE");
return 0;
}

Error Code:
no matching function for call to func(std::string&,std::string&)

I'm learning C++ this summer by myself and have hole punches of qestions, is anyone want to add my msn to discuss it?
here is my MSN jack90830@hotmail.com

thx everyone^^

As I said, you'll have to decide what you want the user to input. Can't you ask them to enter an int and a char, or two chars??
