How do I get a variable to print a string

My question is if there was a way to get an integer variable and then print a specific word when it is set.

What I mean is if someone inputs a value of 1 that is then assigned to variable int fCur, is there a way to print a word (for example Germany) instead of the value 1 ?

cout << "You selected "<< fCur << endl;

I want it to print

"You selected Germany"

not

"You selected 1"

I appologize if this is poorly worded this is my first time using this site

If you want to have each country indexed as follows:

  1. Germany
  2. India
  3. Korea

you can simply use this:

#include <iostream>
#include <string>

int main()
{
    std::string countries[] = {"Germany", "India", "Korea"};
    int country_number;
    std::cin >> country_number; // invalid input is not being checked

    // array indexing starts from 0
    std::cout << "You selected " << countries[country_number - 1] << std::endl;

    return 0;
}

I suggest using an enum to represent the options, and to use if statements that will set the string value:

int main()
{
    enum Country {GERMANY = 1, SPAIN = 2, ITALY = 3};
    cout << "Enter an option: ";
    int fCur{};
    cin >> fCur;

    string str;
    if (fCur == GERMANY)
        str = "Germany";
    else if (fCur == SPAIN)
        str = "Spain";
    else if (fCur == ITALY)
        str = "Italy";
    else
    ;// Handle error


    cout << "You selected " << str << endl;
}

As I guess it you want to create a menu for selecting options something like -

  1. Germany
  2. US
  3. Spain
  4. China etc

If it is only integer 1 that is assigned to Germany then an if condition is enough else to display based on the selection from a menu use switch

int n;
cin >> n;
switch(n) {
     case 1: {
                  cout << "Germany" << endl;
                  break;
             }
     case 2: {
                  cout << "US" << endl;
                  break;
             }
     case 3: {
                  cout << "Spain" << endl;
                  break;
             }
     case 4: {
                  cout << "China" << endl;
                  break;
             }
     default: cout << "Select from valid set of options";
}

Hope this helps.
