• Due before class on Wednesday, February 1
• This homework contains code to be submitted electronically. Put your code in a folder called hw09 and submit using the 204sub command.
• This is an electronic homework and you do not need to print out anything to turn in during class.

Assignment

1. Required reading: Section 5 (Nested loops & Stepwise refinement) from the Unit 3 notes, Note: You do not need to go through the full example in section 5.4 (stepwise refinement from the inside out) if you will be in class.
2. Write a program called counting.c that reads an integer \(n\) from the user, and then uses a nested loop to count from 1 up to 1, then from 1 up to 2, then from 1 up to 3, etc., and finally from 1 up to \(n\).

   Example of running your program:

   roche@ubuntu$ ./counting
   Enter n: 5
   1
   1 2
   1 2 3
   1 2 3 4
   1 2 3 4 5

   Note: be careful not to print an extra space at the end of each line!
