What is event-driven programming explain with example?
Event-driven programming is a programming paradigm in which the flow of program execution is determined by events – for example a user action such as a mouse click, key press, or a message from the operating system or another program. Virtually all object-oriented and visual languages support event-driven programming.
What are the principles of event-driven programming?
As mentioned above, event-driven programming known as a computer programming paradigm that used the occurrence of events to determine the control flow of the program, while objects-oriented programming (OOP) treats datafields as objects manipulated through pre-defined methods only and it constructed over four major …
What is event-driven programming simple?
An event-driven application is a computer program that is written to respond to actions generated by the user or the system. Because event-driven programming is an approach rather than a type of language, event-driven apps can be created in any programming language.
What are the benefits of event driven programming?

What is event driven programming used for?
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.
What is event driven programming model?
In computer programming, event-driven programming is a programming paradigm in which the flow of the program is determined by events such as user actions (mouse clicks, key presses), sensor outputs, or message passing from other programs or threads.
What is Handler CPP?
In C++/CLI, a handle is a pointer to an object located on the GC heap. Creating an object on the (unmanaged) C++ heap is achieved using new and the result of a new expression is a “normal” pointer. A managed object is allocated on the GC (managed) heap with a gcnew expression. The result will be a handle.
