Thread: Return to main menu issue

	while (getMenu != 0)
	{
		// Execute command based on user input
		switch(getMenu)
		{
			// call AddSalesMan function
			case 1:

				break;
			// call and assign report_menu to getReport
			case 2:

				getReport = report_menu();

				} // end while
				break;
		} // end switch
	}// end while 
	system("pause"); // pause the program before it exits	
	return 0;
} // end main

Why I cannot return to main menu from Report Generation?

Code:

switch (getReport = report_menu())
                {
                    while (getReport != 0)
                    {
                        // call QtrReport function
                        case 1:
                            QtrReport();
                            break;
                        case 2:
                            SalesComm();
                            break;
                        getReport = report_menu();
                    } // end while
                }// end switch

Thanks. Another question. Is switch cannot support while loop?

Why not having the switch inside the loop?

No, that's not valid C syntax.

It is valid syntax (see Duff's Device), but it's simply bad style in most instances, including this one.

I stand corrected. Sorry for the misinformation.
