# 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 $$n$$.
