The implementation might look like below. Exception handlers may be provided by "ON statements" in unseen callers to provide housekeeping routines to clean up afterwards before termination, or to perform recovery operations and return to the interrupted procedure.

Graphical editors combine the first two steps: A thread context only needs a CPU stack while actively processing an event, once done the CPU can move on to process other event-driven threads, which allows an extremely large number of threads to be handled.

Event-driven programming

For example, a single left-button mouse-click on a command button in a GUI program may trigger a routine that will open another window, save data to a database or exit the application.

These routines handle the events to which the main program will respond. To add two numbers, storage outside the event handler must be used. Common uses[ edit ] Most of existing GUI development tools and architectures rely on event-driven programming.

The second step is to bind event handlers to events so that the correct function is called when the event takes place.

The third step in developing an event-driven program is to write the main loop. Event handler A trivial event handler[ edit ] Because the code for checking for events and the main loop are common amongst applications, many programming frameworks take care of their implementation and expect the user to provide only the code for the event handlers.

Creating event handlers[ edit ] The first step in developing an event-driven program is to write a series of subroutinesor methodscalled event-handler routines.

This is essentially a finite-state machine approach. Many modern-day programming environments provide the programmer with event templates, allowing the programmer to focus on writing the event code.

This is a function that checks for the occurrence of events, and then calls the matching event handler to process it. In this simple example there may be a call to an event handler called OnKeyEnter that includes an argument with a string of characters, corresponding to what the user typed before hitting the ENTER key.

Most event-driven programming environments already provide this main loop, so it need not be specifically provided by the application programmer.I need to write a Program for a restaurant.

NEED PROGRAM FOR THIS QUES. This program takes an arithmetic operator (+, - *, /) and two operands from an user and performs the operation on those two operands depending upon the operator entered by user. Event-driven programming is the dominant paradigm used in graphical user interfaces and other applications (e.g.

JavaScript web applications) that are centered on performing certain actions in response to user input. Menu driven program to perform various array operations.

Let's get straight to it. You will have an array of menus, with the array elements being the options you want in your menu. Write a program that lets the user perform arithmetic operations on two numbers. Your program must be menu driven, allowing the user to select the operation (+, - *, or /) and input the numbers.
