What is API and is it used in everyday life?
API (Application Programming Interface) is a set of rules that allows different software applications to communicate and share information with each other.
In simple terms, it acts like a messenger that lets one app request data or services from another app without needing to know how it works behind the scenes.
For example, when a weather app shows live forecasts, it may use an API to request weather data from another service. Or ordering food through a delivery app: the app uses APIs to communicate with the restaurant, payment system, and maps service so everything works together smoothly.
