Question

As the title says, is there a dictionary similar to Objective-C’s NSDictionary for C++? I just need a data structure that holds a (key,value) pair and can be added and retrieved.

Answer 1

Use std::map.

For example, to map from integers to std::string:

#include <map>
#include <string>
#include <iostream>

int main() {
  std::map<int, std::string> my_map;
  my_map[3] = "hello";
  my_map[4] = "world";

  std::cout << my_map[3] << " " << my_map[4] << std::endl;

  return 0;
}
