Is it possible to declare a C++ Variable that can contain an Intenger or a String?

Like a 2-in-one-container, See i'm searching for a method to do this, but I'm not gettin anywhere.

Do a struct, which contains an int and a string. (?) Not sure if it is what you want. struct myType { int integer; string str; }; int main() { myType var; var.integer = 3939; var.str = "Hello Planet"; //codes } --- Or you can just declare a string variable, and explicitly convert its contents to integer whenever needed.

It's possible to achieve this using void pointers... But it's messy and difficult to implement here's a code if you want to see how it looks: https://code.sololearn.com/c29KMo1XirBX/?ref=app

STL has you covered!!! auto pair = std::make_pair<int, std::string>(22, "fslkaf");

If you want in the same space in memory, in a way that you can use one or another, there is a structure called union. http://en.cppreference.com/w/cpp/language/union
