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:

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.
