Code:
#include <iostream>
#include <fstream>
#include <cstring>
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
}
return 1;

Ok, iv decided to use system() instead, but now when i try and compile i get an syntex error at line 57 : syntex error before '.' token ? i cant see whats wrong with that line. Please help code below.
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: ";
cin>>choice;
if(choice == '1')
{
cout << "\n\nPlease enter full-path to game start file: ";
cin.get();
cin.getline (s1, 30); // Input goes in$
if (outfile.is_open())
{
outfile<<s1<<"\n";
outfile.close();
}

/* Just break if choice != 1 */
break;
case '2': cout<<"Options\n";

cout<<"2. Go back\n";
cout << "Please enter your choice: ";
cin>>choice;
if(choice=='1')
{
cout << "Please enter full path to config file to edit: "; // ask user for path to config file
cin.get()
cin.getline (s2, 256); // input goes in
system("/usr/bin/pico"); // open up pico to edit config
}
// 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
