While Loops DRILL

What is the primary difference between a for loop and a while loop as explained in the video?

• A for loop is used for conditional statements, while a while loop is not.

• A for loop repeats code a fixed number of times, while a while loop repeats code as long as a condition is true.

• A while loop is always faster than a for loop.

• A for loop can only be used in small programs, while a while loop can be used in large programs.

In the context of the video, what would happen if you used a for loop to move Carol to the wall in a world of varying sizes?

• Carol would always reach the wall regardless of the world size.

• The program would crash if the world was too small.

• The for loop would work perfectly in all world sizes.

• Carol would stop moving before reaching the wall if the world size was larger than expected.

Why is it important to check the condition in a while loop during each iteration?

• To ensure the loop runs a fixed number of times.

• To determine if the program should continue executing the loop or stop.

• To make the code run faster.

• To allow the program to execute other commands simultaneously.

If the condition in a while loop is never met, what will happen to the program? Read each question carefully and choose the best answer from the options provided.

• The program will run indefinitely without stopping.

• The program will execute the loop body at least once.

• The program will terminate immediately.

• The program will skip the while loop entirely.

In the video, what is the suggested syntax for creating a while loop? Read each question carefully and choose the best answer from the options provided.

• `for (condition) { commands; }`

• `while (condition) { commands; }`

• `loop (condition) { commands; }`

• `execute (condition) { commands; }`
