How is the concept of "iteration" defined in programming?

• A. The process of executing a function multiple times
• B. The repetition of a set of instructions in programming
• C. The execution of program statements in sequence
• D. The modification of data types during run-time

Answer: (B)

The concept of "iteration" in programming is best defined as the repetition of a set of instructions. This involves executing a particular block of code multiple times, often with some form of condition to determine when to stop the repetition. Iteration is commonly used in loops, such as `for` and `while` loops, allowing programs to efficiently handle repetitive tasks by automating the execution of the same instructions until a specified condition is met. Understanding iteration is crucial for tasks such as processing items in a list, performing calculations repeatedly, or executing a function until a certain criterion is achieved. This makes option B the most accurate representation of iteration, as it captures the essence of what iteration entails in a programming context.
