Challenge Problems

Push your limits with challenges.

Question 1

Create a MATLAB script that uses a while loop to read user input until the user types 'exit', tally the number of inputs received, and display it after exiting.

💡 Hint: Consider how to compare strings in MATLAB and increment a counter.

Question 2

Write a MATLAB function using a while loop that returns the factorial of a number. The function should prompt the user for input and continue to do so until a positive integer is given.

💡 Hint: Think about validating the input to ensure it's a positive integer.
