It's useful when you don't know beforehand exactly how many times you need to run the code. Here's how it works: Initialization: You start by setting up a variable that will control the loop. This variable typically holds a counter or a value used in the condition. Condition Check: The loop then checks a condition. This condition is a boolean expression that evaluates to either true or false. Code Execution: If the condition is true, the code block within the loop gets executed. This code block can contain various statements and operations you want to repeat. Update: After the code executes, the loop typically updates the control variable. This update might involve incrementing or decrementing a counter, or modifying a value used in the condition. Repeat: The loop then goes back to step 2 and checks the condition again. This cycle continues as long as the condition evaluates to true. Once the condition becomes false, the loop terminates. Here's an analogy: Imagine you're waiting in line for coffee. While you haven't reached the counter yet (condition true), you keep moving forward (code execution). Once you reach the counter (condition becomes false), the loop (waiting in line) stops. While loops are essential for repetitive tasks where the number of iterations isn't predetermined. They offer more flexibility compared to for loops, but it's crucial to ensure the loop eventually terminates to avoid infinite loops.
