**Lab 5 Due Monday Oct 15**

{{:lab:lab_5.pdf|Lab 5}}

**Hints**
  - Your program should not prompt the user.
  - The user should enter the length of the list (n) then hit return. Then enters the n numbers
  - When you display error message or the answer, your program should exit
  - Check what is the return value of scanf. For more of a hint, scanf returns EOF when there is no data to read

**Lab test 3  ** C and bash Nov. 30, dec. 3

Some of you asked me about "practice test". I have a problem with that, any example I put on this page will be interpreted by many, not all, as this is how the test will be.

Instead, here are some example code tests to test your ability in C. [[https://www.w3resource.com/c-programming-exercises/]]
