A programmer uses a while loop to validate user input; however, the loop never terminates, continuously prompting the user. What is the most likely cause?
A programmer uses a while loop to validate user input; however, the loop never terminates, continuously prompting the user. What is the most likely cause?
- The program's output is being redirected back as input.
- The loop control variable is not being updated correctly, leading to an infinite loop. (correct)
- The `while` loop is the incorrect type of loop for input validation.
- The loop is missing an `if` statement to handle invalid input.

Study Notes
- An infinite loop is a loop that never ends because the termination condition is never met or is incorrectly written.
- Input is data that is provided to a program for processing.
- A loop control variable determines whether the loop will continue running or stop and is often incremented or modified within the loop.
- A nested structure is a programming construct where one control structure (like a loop or a conditional statement) is placed inside another.
- Output is data that is produced by a program and presented to the user or another system.
- A pretest loop evaluates its condition before executing the body of the loop, like a while loop.
- Pseudocode is a simplified, human-readable version of a program's code that outlines the logic without strict syntax rules.
- Repetition (iteration) refers to the act of executing a set of instructions multiple times, generally using loops.
- Selection is a control structure allowing a program to choose between different actions based on conditions, and is similar to a branch.
