What's a simple way to write a calculator in C++ that can handle an infinite amount of numbers?

Writing 2 number calculators is obviously very easy as you only have to define 2 double variables, but as soon as you add more things get kind of complicated and I'm not sure where to go from there.

Here's my 2 number calculator (nothing special):

#include <iostream>
using namespace std;

int main()
{
double num1;
double num2;
char again;
char operation;

do
{
cout << "Please enter the equation you wish to solve. " <<endl;
cin >> num1 >> operation >> num2;

switch(operation)
{
case '+':
cout << "=" << num1 + num2 << endl;
break;

case '-':
cout << "=" << num1 - num2 << endl;
break;

case '/':
cout << "=" << num1 / num2 << endl;
break;

case '*':
cout << "=" << num1 * num2 << endl;
break;

case '%':
cout << "=" << num1 % num2 << endl;
break;
default:
cout << "Invalid operation. "

}
cout << "Solve another equation? (Y/N)" <<endl;
cin << again;
}

while (again=='y'||again=='Y');
}

I heard it can be done with arrays or something along those lines but I'm not sure how to put it all together.

Help!
