Event driven programming is good as it sits there idle until the event trigger occurs and it is quick to respond to this. On the other hand, it may be unsuitable for event driven programming because you wouldn't want to have to trigger the alarm before getting out of the building, you would just want to get out of there as soon as possible. This would also annoy the users who are using them, an example could be lifts, they would be constantly going up and down the lift shaft, as well as opening and closing the door all the time , users would not be able to trust it or use it, this would mean that the lift is pointless and it does not complete its purpose that it was designed and created for. Yet, to say that non-graphical event driven applications will fade away in the near future seems unlikely, most products don't need a fancy interface and are used purely for functionality yet we can't say for sure that these won't be replaced as technology becomes more innovative and creative. You then have the movement of cars which again needs interaction by a human being.
If children happen to be around the washing machine they can potentially get hurt because the washing machines are not soft and can really hurt someone. Event driven programs can be limited to their Graphical user interface. When the sensor senses a movement then there is an event that will take place, this is an example of how the event driven program works, the sensor will only move to the task once it has received movement, only after this will it fire an event. Create onscreen help to assist the users of a computer program. It will include everything from examples of an Event driven program, Simple architecture of how an event driven program operates. But it will certainly need less code. Without them we would have lots of difficulty living our lives, washing and microwaving would become more manual and computers couldn't receive input without devices such as mice and keyboards.
Some concepts like inheritance of common interfaces are a bit harder to express using C they will need more code , but some may argue that the resulting software may be easier to understand from a maintenance point of view than the C++ equivalent. It also boosts the look of your car; meaning makes your speed meter, petrol meter and other meters look attractive. You then have to type your text and select the contact you want to send it to. Another good example would be a smoke alarm. The progression of this technology also goes hand in hand with gaming experiences.
Sequential Programming 2 Flow of a typical sequential program Prompt the user Read input from the keyboard Parse the input determine user action Evaluate the result Generate output Repeat Example DemoTranslateEnglishConsole. With washing machines they are really big and take up a lot of space in your house. Event driven languages for non-graphical applications: Event driven languages are suitable for many non-graphical applications, this can be on computers or in every day life. In this post I will describe how suitable is Event Driven Language for non graphical applications. A washing machine cannot assume because the code means that it will always perform the same things. My class is made up of computers.
Washing machines and dish washers both use timers to know when tasks are finished, when the timer ends, an event is ran to stop the washing machine and the dish washers cycle. The event is the alarm going off and alerting people to the smoke. There many non-graphical applications that are suitable with event driven programming. Evaluate Television Set-top Boxes D1 You now have television set top boxes which is basically a square shaped box and it only operates by the usage of a remote control. Examples of Languages that use event driven programming: Visual basic uses event driven programming. An event driven programme here is not really.
In C++ you'll have classes. Such a motion sensors used in traffic lights to sense incoming cars. As each of the objects has their own data, it is easy to re-use the different parts all around the program. The service is split into components, service and. Once the button is touched, the application running the hob would need to make an action happen, due to the event created by the user. However for non-graphical applications you could use procedural programming, but event driven is now used in everyday products and its the way forward. When we look at operating systems, games, most websites.
You can dry wash clothes, you can super wash clothes, washing machines in most cases are really easy and simple to use. My final example of event driven languages being used in non graphical applications is smoke alarms. This happens when you open the disk drive because it will alert you to whether the disk drive is opening. You will have to hire a professional to fit the car engine management system in your car. Say the current heat is 9 oc; the desired heat is 5 oc. All of which would not have been possible if it was not for an event driven program. The event that is involved in this instance would be when the sensor on the inside detects the smoke, it starts bleeping and alerting everyone in the building.
Finally the sensor records the temperature as 4 oc which is below the desired temperature. It does not seem to us that Event driven will be used completely by graphical applications in the future. Pre-defined functions: A pre-defined function is a function that is built into the programming language, for example system. With car engine management systems both inputs and outputs are available. Event handling means that the object name plus event name must be entered for the object to function. Two examples of devices that are used in everyday life, that uses event driven language can be washing machines and disk washers, they are turned on but wait for a trigger to happen, which is the users input, which can use buttons, when this happens the event is then carried out.
