Hi,

i have worked my way through my c++ book but it dont cover what i need to finish my program, i have been told i will need to use system() or execl for my program. (1.) I need to be able to ask user for file to open and be able to open that file for editing and then save and return back to menu when done. 2. I need to be able to execute the path from games.db (like say line 1 is /home/twirl/bf1942/start.sh i need it to execute that line and so forth depending on how many lines are in games.db and what the user wishes to run. (sourcode at http://pastebin.com/356387 ) and i was wondering if anyone could tell me or show me a sample of code please?

Thankyou

Using system is really very simple:

Code:

char buf[256];

sprintf(buf, "some_program %s", filename);
system(buf);
