#API that stands for #ApplicationProgrammingInterface refers to the set of rules, usual definitions and tools that helps in the creation of #applications and #software. The core benefit of a good API is that it provides structures that diminish the difficulties in creating a #program. The provided structures are further combined by the #programmer. API could be of multiple types however it usually includes requirements for #object #classes, remote calls, #datastructures or routines.
Examples of different forms of APIs are:
• Java API
• C++ Standard Template Library API
• POSIX
• Microsoft Windows API
An API may be for a web-based system, #operatingsystem, #databasesystem, #computerhardware, or #softwarelibrary.
Why Should APIs be used?
#Application #Programming #interfaces brings ease to developers by providing them ready-made building blocks, which they just had to use. Likewise the #GraphicalUserInterface that helps in using programs easily, APIs helps the developers to use technologies in an easy way. API conceals the tricky implementations and makes the programmer view or use particular action or objects that he needs. This relaxes the mind of programmer and allows him to work smoothly. For example, to copy any file from one location to another, the #developer doesn’t have to learn file system operations at the backend since API for file input/output provides convenient function to perform this task
