Making a presentation in C ++ (I'm stuck)

Question

I am working on a school project (I'm in seventh grade) and why I want to be a programmer. I have to make an idea of ​​what a computer programmer is and what he does. I thought it would be nice to write my own presentation. I already encoded something, but I was stuck. This is what I still have

    #include <iostream>
    #include <string>

    using namespace std;

    int main()
    {
      string question;
      cout << "Type [1] to begin...";
      cin >> question;
      if(question == "1")
    {

      cout << "A computer programmer figures out the process of 
   designing, writing, testing, debugging, and maintaining the source c 
   ode for computer programs";   

         return 0;
     }

    }

Now, what I want to do is add an instruction like “goto”, where it can go to something like “int second ()” and cout something new like “what are programming languages?”. and then a description of what they do after the user enters something like yes. Any help would be greatly appreciated. I am really new to C ++. Thank:)
