using namespace std;

 

int main()

{

 char string[30];        // set char size to 30 for input

 ofstream outfile("games.db", ios::app);

 myeditor="xterm -e /usr/bin/nano" // set path to nano



// Start Main Menu

 

 char choice='\0';//NULL;

 bool finished=false;

 while (finished != true) 

 {

  cout<<"MAIN MENU\n";

  cout<<"1. AddGame\n";

  cout<<"2. Options\n";

  cout<<"3. RunGame\n";

  cout<<"4. Exit\n";

  cout << "Please enter your choice: ";

  cin>>choice;

  cout<<"\n\n";

 

  // Start function for submenu

  switch(choice) 

  {

   case '1': cout << "1. Add Game To DB\n";

             cout << "2. Go back\n";

             cout << "Please enter your choice: ";

             cin>>choice;

 

             if(choice == '1')

             {

              cout << "\n\nPlease enter full-path to game start file: ";

                          cin.get();

                          cin.getline (string, 30); // Input goes in$

                          if (outfile.is_open())

                          {

                           outfile<<string<<"\n";

                           outfile.close();

                          }

                         }

             /* Just break if choice != 1 */

             break;

   case '2': cout<<"Options\n";

             cout<<"1. Edit Game Config\n";

             cout<<"2. Go back\n";

             cout << "Please enter your choice: ";

             cin>>choice;

             

             if(choice == '1');

             {

             cout << "Please enter full path to config file:";

              cin.get()

               cin.getline (string, 30); // input goes in

              myeditor += string;  exec(myeditor.c_str());

             }                           

               

/* Just break if choice != 1 */

             break;





          // Here we would check 'choice' and probably move to another functi$

             cout<<"\n\n";

             break;

   case '3': cout<<"Run Game";

 

                 // Here we would check 'choice' and probably move to another functi$

             cout<<"\n\n";

             break;

   case '4': //Finished so set finished 'true' to break out of loop

             finished=true;

             cout<<"Exiting....\n";

             break;

   default:  //If choice !=1/2/3 then do what it says here

             break;

 

             //  end functions

  }

  choice='\0'; //NULL

myeditor is undeclared, and your instruction is unterminated.

 char string[30];        // set char size to 30 for input

 ofstream outfile("games.db", ios::app);

 string my_editor;     // create string my_editor

 my_editor = "xterm -e /usr/bin/nano"      // set path for nano 



 // Start Main Menu

 

 char choice='\0';//NULL;

 bool finished=false;

 while (finished != true)

Code:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
 
int main()
{
 char s1[30],s2[256];        // set char size to 30 and 256 for input
 ofstream outfile("games.db", ios::app);

 // Start Main Menu
 
 char choice='\0';//NULL;
 bool finished=false;
 while (finished != true) 
 {
  cout<<"MAIN MENU\n";
  cout<<"1. AddGame\n";
  cout<<"2. Options\n";
  cout<<"3. RunGame\n";
  cout<<"4. Exit\n";
  cout << "Please enter your choice: ";
  cin>>choice;
  cout<<"\n\n";
 
  // Start function for submenu
  switch(choice) 
  {
   case '1': cout << "1. Add Game To DB\n";
             cout << "2. Go back\n";
             cout << "Please enter your choice: ";

             }
