Develop a computer program to solve a problem using control structures : While Loops

The video tutorial explains the differences between for and while loops, highlighting that for loops have a predefined number of iterations, while loops depend on a condition. An example in Jupyter Notebook demonstrates a while loop that initially runs indefinitely due to an unchanging condition. The tutorial then shows how to fix this by incrementing a variable within the loop, allowing it to terminate once the condition is false.

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

• A for loop is used for infinite loops, while a while loop is used for finite loops.

• A for loop iterates a predefined number of times, while a while loop continues until a condition is false.

• A for loop iterates based on a condition, while a while loop iterates over an iterable.

• A for loop can only iterate over numbers, while a while loop can iterate over any data type.

In the given example, why does the while loop run indefinitely?

• Because the loop is not inside a function.

• Because the condition is always false.

• Because the condition is always true and the variable is not updated.

• Because the loop is missing a print statement.

What is the purpose of the += operator in the while loop example?

• To add 1 to the current value.

• To subtract 1 from the current value.

• To multiply the current value by 1.

• To divide the current value by 1.

How many times does the while loop iterate in the final example?

• 10 times

• 9 times

• 8 times

• 11 times

What happens when the condition in a while loop becomes false?

• The loop restarts from the beginning.

• The loop continues to run.

• The loop throws an error.

• The loop terminates and exits.
