Idea to source code converter in C++

#include <iostream>
#include <fstream>
using namespace std;
int main()
{
    string this_step;
    string total_code;
    int choice;
    string text;
    cout<<"Hello , I am zero005 , a bot developed by Ahmed Saber , to help you create a c++ app easily , as I will give you the source code of the app you want to create , but first you must tell me all about this app..."<<endl<<endl<<endl;
    // preparing libraries
    again:
    cout<<"First step , here I want to know what you want to use."<<endl<<"Choose by only typing the number of choice then pressing Enter"<<endl<<"1- I want to print text on the screen"<<endl<<"10- I added everything , Let's go to next step"<<endl;
    cin>>choice;
    if (choice==1)
    {
        this_step="#include <iostream> using namespace std;";
        total_code=total_code+this_step;
        goto again;
    }
    else if (choice==10)
    {
        this_step="int main() {";
        total_code=total_code+this_step;
    }
    // let's ask the user about what will be done first then second ...etc
    one_more:
    cout<<endl<<"choose a step to be done"<<endl<<"1- print something"<<endl;
    cin>>choice;
    if (choice==1)
    {
        cout<<"Enter the text you want the app to print (Type without using space)"<<endl;
        cin>>text;
        this_step="cout<<'"+text+"'<<endl;";
        total_code=total_code+this_step;
    }
    // end
    total_code=total_code+"}";
    // create a text file with the source code
    ofstream MyFile("source code.txt");
    MyFile<<total_code;
    MyFile.close();
}
