From your i could only understand is this you need a dictionary to be implemented in C++ which i have done and sharing with you. Do have a look and let me know if anything else needed.

there is only one .cpp file required which you can create with any name and paste your code it will run.

std::map is the standard library which is used to implement dictionary in c++. It uses key value pair where keys are unique and values are associated with them map is STL in C++.

#include <string>
// Map is the concept through which we implement dictionary in C++, So including the header files.
#include <map>
#include <iostream>
using namespace std;

int main()
{
   // creating the map with key and value pair
   // Like in dictionary we have meaning for word here for a particluar key we have a value.
   map<int, string> m;
   m[1] = "A";
   m[2] = "B";
   m[3] = "C";
   m[4] = "D";
   m[5] = "E";
   m[6] = "F";

   // Loop through and print elements from map
   for (auto i : m)
   {
       cout << i.first << " : " << i.second << endl;
   }

   // Fetching the value based on key
   cout << "The value for key 1 is : " << m[1] << endl;

   // Inserting a key at end.
   m[7] = "9";
   // Modifying the existing key and changing the value from C to Z
   m[3] = "Z";

   // Loop through and print elements from map
   for (auto i : m)
   {
       cout << i.first << " : " << i.second << endl;
   }

  
return 0;
}
