While Loop in Programming
The while loop is a fundamental control structure in programming that allows you to execute a block of code repeatedly as long as a specified condition evaluates to true. This is particularly useful for scenarios where the number of iterations is not known beforehand and depends on dynamic conditions.
Key Features:
- Condition Evaluation: The loop checks the condition before executing the code block, ensuring that the code runs only when the condition is true.
- Use Cases: Commonly used in scenarios such as iterating through data structures, waiting for user input, or performing repeated actions until a certain state is reached.
Example Use Case:
In the context of the Microsoft MakeCode platform, the while loop can be used to control LED displays, manage user interactions, or handle real-time data processing. For instance, you can create a diagonal line on an LED screen by plotting points in a loop until a certain condition is met.
