Depends what you want your symbol table to store. Lets say it is a string and a class of base type Symbol. This would look like

#include <map>
#include <string>
using namespace std;

class Symbol;
map<string,Symbol*> lookup;

You may have to add #pragma ... if you don't want the warnings about the symbols being over 255 characters.

Anyway, to add something to the table

lookup[something] = new SymbolChild ();

To get the symbol

Symbol* sym = lookup[something];

It will return 0 if the symbol has not been added.
