How to use a string as a variable name in C++? [duplicate]

Answer 1

You can't in C++.

One thing you can do is use a form of std::map<std::string, std::vector> to store name to vector map.

Answer 2

You don't.

Variable names are a compile-time construct. The contents of a string are a run-time concept (string literals are slightly different, but those won't work either). Unless you write a specific mapping layer (which maps a string name to some object), you cannot just use a string as a variable name.

Or a type name for that matter.
