[] and = operators together

[miladrahimi93]

Hello guys!
I wanna use [] and = operators together.

   className x();
   x[value1] = value2;

How I can do it and get two values in my class?

className x();

This is a mistake.
It does not define an object named x. It declares a function named x() that returns a className and takes no parameters.

It all revolves around your operator[] that you overload for your class.
First, if value1 doesn't exist, it has to be added.
Second, return a reference to whatever value1 maps to, so that it can be assigned to.

What you are trying to achieve is very similar to the operator[] of std::map.

Do you want to overload two operators in your class? In the code snippet, you seem to have called only one operator[]. The = operator is not your class assignment operator.
