What is the difference between while and for loops?

• A. A while loop iterates over a range, while a for loop checks a condition
• B. A while loop is used for fixed iterations, while a for loop is indefinite
• C. A while loop continues based on a condition, while a for loop iterates over a collection
• D. A while loop and for loop are identical in function

Answer: (C)

The correct answer highlights the fundamental difference between while loops and for loops in programming. A while loop operates based on a specified condition that must evaluate to true for the loop to continue executing. Essentially, the loop will keep iterating as long as that condition holds true; this makes while loops particularly useful in scenarios where the number of iterations cannot be determined beforehand.

In contrast, a for loop is typically used to iterate over a collection, such as a list or a range of numbers. It allows you to execute a block of code for each item in that collection, which lends itself well to scenarios where you need to perform operations on each element in a sequence.

This distinction is crucial in programming, as it determines how the loops are utilized based on the needs of the code. For instance, you might use a while loop for reading input until a certain value is provided while using a for loop to perform actions for each item in a predefined list.

The other options do not accurately capture the behaviors of the loops. A while loop does not iterate over a range (as suggested in the first choice), and it is also not limited to fixed iterations. The second choice mistakenly states that a while loop is for fixed iterations; in reality, it is more about
