How do I return the value of an integer with the same name as a string

[rakan]

Is there a way to input the name of a string and return the value of an integer that has the same name as the string? For example, suppose I have this program...

#include <iostream>
using namespace std;

int main(){
    string nameofstring = "test";
    int test = 1;
    
    cout << nameofstring;  //outputs the word "test", I would like it to output the integer 1.  How do I do this?

    cin.get();
    return 0;
}

I would like it to read the name of the string and find the return the integer of the same name as the string. I think it can be done in Java using getInteger( String nm, int val ). Is this possible in C++? Thanks.

You can't do exactly what you're looking for in c++. It's known as reflection in other languages and is absent from C++.

However, you can get pretty close by using a std::map

#include <iostream>
#include <map>

using namespace std;

int main(){
    std::map<string, int> namedNumMap;
    namedNumMap["test"] = 1;
    
    cout <<  namedNumMap["test"] ;  //outputs 1.  

    cin.get();
    return 0;
}

it's not perfect, but it's as close as you're gonna get in C++

Thx ChaosEngine, I'll give it a try.

Don't forget to #include <string> if you are using the string class (even if it appears to work without it).
