Hey there;
I've run into a problem!
I have a program that is supposed to do multiple things.
Therefore - I have a menu (switch statements).
Is there any way I can make it so when 1 statement finishes, it can go back to the main menu? I can add a case for X (10 we'll say) that will end the program.
If there isn't a way.. how should I do this menu?
Jump to Postuse a while loop
bool done = false; while( !done ) { //show menu and execute switch statements or other stuff }You can use other kinds of loops too, depending on what you want it to do.
Jump to PostYou didn't put the menu in a loop as I suggested earlier.
bool done = false; while( !done ) { // Menu cout << "INFR1100U final project: \n"; cout << "\n***********MENU**************\n"; cout << "_____________________________\n"; cout << "Add/Remove Options\n"; cout << "1. Add New User\n"; cout << "2. …
use a while loop
bool done = false;
while( !done )
{
//show menu and execute switch statements or other stuff

}Still ends after I finish entering a user.
You didn't put the menu in a loop as I suggested earlier.
bool done = false;
while( !done )
{
// Menu
cout << "INFR1100U final project: \n";
cout << "\n***********MENU**************\n";
cout << "_____________________________\n";
cout << "Add/Remove Options\n";
cout << "1. Add New User\n";
cout << "2. Remove an Existing User\n";
// etc etc etc
}My trigger works the same way.. it still doesn't work. Is it because of the breaks?
you need to make a couple logic changes.
while(intChoice!=10)

}Where?
Where what? All I did was change what you posted and moved that while statement to the top of the menu.
