How can I define a function in a C++ class that takes two objects as arguments? [closed]

Question

I want to create a function in a C++ class or in the files of the class, but I want it to take two objects as arguments, shush like:

    float function (Object a, Object b){
        return float;
    };

But I don't want to write in the main program:

    Object a;
    Object b;
    float c;
    c = a.function (a, b);

I want to main program to look like this:

    Object a;
    Object b;
    float c;
    c = function (a, b);

So, where do I have to define this function?

Answer 1

C++ is just C with classes (and other stuff). You can define a function like in C in any .cc file

float youFunctionName(Object a, Object b){

    float returnNumber;

    //do whatever you want...

    return returnNumber;

}

and call from any other function or method as normal function:

c = youFunctionName(a,b);
