These activities require the use of your "Programming in C" zyBook:
The online nature of the zyBook encourages you to try things out and gives you immediate feedback. There is no limit on how many attempts you can make on the zyBook activities, and all that will be counted for your grade is completion of the required activities. Note however that your solutions are not permanently stored by the system, so if you refresh the current page or move to a different page, your answers will be lost. This feature is intentional, so that students can practice their understanding of the material as many times as they wish to.
Nothing. The system will keep track of all completed tasks for each individual student.
