C Tutorials and Sample Problems

Using Pointers to Send Information Back From a Function

Instructions for doing this tutorial:

1. Read the Discussion, Example, and Summary. Ask questions as needed.
2. Do the first practice problem, as follows:
   • Do Practice Problem 1 (TODO 1 and TODO 2) in the Practice Problems.
   • You should be able to tell from running the program whether or not it is correct.
   • If you are not able to get the program correct, ask questions before proceeding. It is much better to ask questions than to just look at the answer.
   • AFTER you believe that you have a correct solution to Practice Problem 1, compare your answer to our Solution to Practice Problem 1. Ask questions as needed.
3. Do the second practice problem similarly, as follows:
   • Do Practice Problem 2 (TODO 3 and TODO 4) in the Practice Problems.
   • You should be able to tell from running the program whether or not it is correct.
   • If you are not able to get the program correct, ask questions before proceeding. It is much better to ask questions than to just look at the answer.
   • AFTER you believe that you have a correct solution to Practice Problem 2, compare your answer to our Solution to Practice Problem 2. Ask questions as needed.
