While Loops
A while loop is a fundamental control flow structure in programming that repeatedly executes a block of code as long as a specified condition remains true. It is used for iterative tasks where the number of repetitions is not known in advance, such as processing data until a sentinel value is encountered or waiting for user input. While loops are a core concept in most programming languages, enabling tasks like input validation, game loops, and data streaming.
Developers should learn while loops to handle scenarios where iteration depends on dynamic conditions rather than a fixed count, such as reading files until the end, polling for events in real-time systems, or implementing retry logic in network operations. They are essential for writing efficient and flexible code in applications like simulations, data processing pipelines, and interactive programs where termination is condition-based.
