Challenge: Weekday Switch

Task
test

Swipe to begin your solution

Write a program that takes an integer from 1 to 7 and prints the corresponding day of the week.

  1. Use a switch statement to compare the value of day to numbers 1-7.
  2. For each case (1 to 7), print the corresponding day of the week.
  3. Add break after each case to prevent fall-through.
  4. Add a default case to handle invalid inputs (numbers outside 1-7). In this case, print "Error".
