Über diesen Kurs

The third course in the specialization Introduction to Programming in C introduces the programming constructs pointers, arrays, and recursion. Pointers provide control and flexibility when programming in C by giving you a way to refer to the location of other data. Arrays provide a way to bundle data by guaranteeing sequences of data are grouped together. Finally, recursive functions—functions that call themselves—provide an alternative to iteration that are very useful for implementing certain algorithms....

End of course project was challenging and fun. Lots of opportunity to learn how to debug memory issues with valgrind.

Very well designed hands-on training course for developing a real software program in C.

Really nice and the project is really challenging.

A very good course if you just look at the programming part. But most of the time you try to find testcases what the programmer could have done wrong ( without knowing the course). That's pure luck and does not help to improve my C skills....

Very tricky. Much trickier than the earlier courses in the specialization. This is to be expected because pointers are slippery. My only complaint would be that the course needs more basic instruction in Git. I ran into some major issues with github and lost hours trying to fix them. Git is a great skills and should be included in the course, but I think we need a little more guidance.

Very bad tool use for uploading assignment

The course requires 100% perfection in order to move on from one assignment to the next in the course as well as from one course to the next within the specialization. This expectation becomes incredibly challenging based upon 1) the minimal teaching videos, 2) lack of programming examples and practice exercises, 3) requiring students to learn and implement tools not addressed in the lessons (e.g. qsort() and void * variables), and 4) heavily relying upon reading out-of-context selections from a textbook co-written by one of the instructors.

The structure of this course consistently poses a problem (see the discussions) when a student struggles to understand the material or cannot figure out how to fix their program, even when submitting screenshots of bugs within the course grader. Too often, the instructors and/or their staff ignore questions and do not always provide feedback to assist the student in understanding why their code does not work (once again see the discussions).

These flaws could be overlooked if auditing these courses were an option, but at $49 per month these courses should be designed to enable students to learn foundational concepts without demanding absolute perfection. For students who want to learn C Programming, a much better option would be cs50x and/or C Programming with Linux through edX. Both of these courses can be audited for free and do not possess any of the issues mentioned above.

Great course. They did a great job in explaining key concepts like pointers and arrays, which are usual subjects with which students struggle.

The course itself is great. The grading system is a bit frustrating because you don't know what the actual tests are. Some idea of what they are actually testing would be a great learning experience.
