C++ same function parameters with different return type

Question

I need to find some way to mock an overload of a function return type in C++.

I know that there isn\'t a way to do that directly, but I\'m hoping there\'s some out-o

Answer 1

The answer is simple just declare the function returning void* type and in the definition return a reference to the variable of different types. For instance in the header (.h) declare

void* RetrieveValue(string dataString1);

And in the definition (.cpp) just write

void* RetrieveValue(string dataString1)
{
    if(dataString1.size()>4)
    {
        double value1=(double)dataString1.size();
        return &value1;
    }
    else
    {
        string value2=dataString1+"some string";
        return &value2;
    }
}
