Challenge: Weekday Switch
Task
Swipe to start coding
Write a program that takes an integer from 1 to 7 and prints the corresponding day of the week.
- Use a
switchstatement to compare the value ofdayto numbers 1-7. - For each case (1 to 7), print the corresponding day of the week.
- Add
breakafter each case to prevent fall-through. - Add a
defaultcase to handle invalid inputs (numbers outside 1-7). In this case, print"Invalid day".
Note
Please note that in our system, the counting of days in the week starts on Monday. So, the first day is Monday, the second is Tuesday, and so on.
