What is Iteration
In computer science and programming, iteration refers to the process of repeating a specific set of instructions or code multiple times. This is often done through loops, such as for loops and while loops, to execute the same task until a condition is met or a specified number of repetitions is reached.
Iteration is essential in algorithms and programs where repetitive tasks are performed, such as traversing arrays, processing lists, or running calculations. Each pass through the loop is called an iteration, and the process continues until the loop's termination condition is satisfied.
Examples of Iteration in Programming:
- For Loop: A loop that repeats a block of code a fixed number of times.
- While Loop: A loop that continues executing as long as a specified condition is true.
- Do-While Loop: Similar to a while loop, but the code executes at least once before checking the condition.
