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

Whether it is an overload or a specialization, you'll need the information to be in the function signature. You could pass the variable in as an unused 2nd argument:

int RetrieveValue(const std::string& s, const int&) {
  return atoi(s.c_str());
}
double RetrieveValue(const std::string& s, const double&) {
  return atof(s.c_str());
}

int i = RetrieveValue(dataString1, i);
double d = RetrieveValue(dataString2, d);
