How to exit without exit?

Home work agian.

I'm required to write a sales analysis program.

One of the function dose enter a new salesperson, it will prompt for personal detail. but if user keys in -1 at any point, it will cancel process and return to main menu options.

BUT according the programming standards of this, " GOTO statement, BREAK keyword and EXIT function are NOT allowed in any program. In C++ the use of Return to jump out of a function premeaturely is not Structured and therefore not allowed".

What can I do ?Thanks!!

Ok.. here is a very stupid idea..
Multithread, one thread that is suspendd for the main menue. One for input and one for checking for '-1'. If the third thread finds '-1' make it suspend the input and checking (itself) threads and activate the main meue thread. Although I am sure that a more elegant and easier solution is out there somewhere...
Instead of exit you can use abort().. for breaks use catch(?). And for goto use switch(?) although that would be hard.... I don't see how you need those though...

Thank you for your reply!
I'ver got an idea too, how about compare the input string with "-1".

while(!strcmp(ID,"-1"))
{
    cin << firstName;
    while(!strcmp(firstName,"-1"))
    {
         cin << lastName;
     }
}

How is that? Haven't tried no my code.

oh.. ok.. you have to make the entire string -1.. well then your idea is ok.. I though you were dealing with multiparagraph multiple strings that were constantly changed.... ya.. for this purpace your idea is the best..
