Fundamentals of Object-Oriented Programming - C++ - Loops - WHILE

The video tutorial explains the concept of while loops in programming, highlighting their use when the number of iterations is not known beforehand. It provides two examples: one where user input determines loop termination, and another where numbers are raised to the 4th power until a condition is met. The tutorial emphasizes understanding loop conditions and expressions.

What is the primary reason for using a while loop instead of a for loop?

• When the loop needs to run infinitely

• When the number of iterations is unknown

• When the loop needs to run only once

• When the number of iterations is fixed

In the example provided, what value does the user need to input to terminate the while loop?

• 99

• 1

• Any negative number

• 0

What is the test expression used in the first while loop example?

• N is equal to 99

• N is greater than 0

• N is less than 100

• N is not equal to 0

What is the initial value of the variable 'power' in the second while loop example?

• 1

• 0

• 10

• 100

What condition must be met for the second while loop to terminate?

• The number is greater than 9

• The power value is exactly 10,000

• The number is less than 10

• The power value exceeds 10,000

How is the power calculated in the second while loop example?

• NUM times NUM

• NUM times NUM times NUM times NUM

• NUM times NUM times NUM

• NUM plus NUM plus NUM plus NUM

What is the maximum number that is raised to the 4th power in the second example?

• 9

• 8

• 10

• 11
