Hey all,
I have a program, that starts with a menu of options (1-9).
for instance if i choose option 3, it then asks me a series of questions.
Im looking to stop execution of those questions (in the middle, via a special keyword), and return to the main menu.
how can i do this??

Currently i have a keywork "main" and it calls the main fuction, displays the menu, and you can continue from there. HOwever when that exits, the program continues execution where the "main" was called. this cannot happen.

Any ideas??

thanks so much!

Josh

I am not sure that I got you questions or not;
But I think you should write some thing like this:

while (true)
{

// Give a key from user; i.e. 1-9 or for example 'q' for exiting from the program:

// swith on the readen key if it is not 'q' else break
{
case '1':
// A special functions; Which asks a series of questions
break;

case '2':
// A special functions; Which asks a series of questions
break;
.
.
.

}
}

yes, something like that, however i need a little more logic, each case statement directs to a certain function.

And for instance case 1, will redirect to a newItem function, and ask a series of questions. I need the ability to break in the functions (at any question) and not return execution) and redisplay the main menu, (back to the case statementS)

figure a quick hack.

Using a goto statement, i just goto the last line of the function, and program execution continues there.

thanks anyway

I really suggest you not to handle it with "goto"! I am sure always there is a better way than a goto; for example here you can return a dummy value and whenever you need to check whether the function exit normally or not check the return value and ...

yes, i understand that, however i cannot wait until the end of the function, i need a way to check after each user input, if we should exit the function or not..
is there an efficient way of doing this??

When you do your user input checking you want an if invalid/keyword, return(EARLY_TERMINATION_CONSTANT) to get back to the case code, where the return value is checked and if it is EARLY_TERMINATION_CONSTANT, you break and the main menu loop runs again.

Edit: I dont think you should ever call the main function, and also shouldnt use GOTOs.
