What is the difference between a "while" loop and a "for" loop?

What is the difference between a "while" loop and a "for" loop?

• A. A "while" loop runs a fixed number of times, while a "for" loop runs based on a condition
• B. A "while" loop continues as long as a condition is true, while a "for" loop runs a specific number of times
• C. A "for" loop always executes, while a "while" loop might not
• D. A "for" loop can handle multiple conditions, while a "while" loop cannot

Answer: (B)

A "while" loop continues executing as long as a specified condition remains true. This means that the loop's execution is dependent on the state of the condition, which can lead to an indefinite number of iterations if the condition is never met to stop the loop. This flexibility makes "while" loops suitable for situations where the number of iterations is not predetermined and is based on dynamic conditions. On the other hand, a "for" loop is designed to run a specific number of times, usually defined by an iterable range, a counting variable, or with a clearly specified beginning and end. This makes "for" loops predictable in terms of iteration count, which is particularly useful when you know in advance how many times you want to execute a block of code. This distinction highlights that a "while" loop is conditional and indefinite, whereas a "for" loop is typically structured for a finite number of iterations, making option B the accurate description of their differences.
