About the Course

Building on the course Programming Fundamentals, this course will teach you how to write code by first planning what your program should do—an important approach for novice and professional programmers. You will learn how to compile and run your program, and then how to test and debug it. This course builds on the Seven Steps you have already learned and provides a framework for systematically testing for problems and fixing them, so you can find and fix problems efficiently....

Instructors and the instructors who moderate the forums are great. It is a bit different way to look at programming but it makes sense and I would recommend to anyone who wants to learn C

It is actually a hard course i guess you need to have at least the basics as some of the assignments were really hard take me a lot of time to do them. especially the poker assignment

The Readings sections in the course need a major revision. I had to spent hours trying to understand what was being conveyed. Also the README files of the assignment tasks. The language used was confusing and many times the instructions were not clear. I would suggest a revision of all the problem statements and readings.

Alright course so far. However, to me, the README seem cryptic at times. There are times when I was saying, "WTF are they trying to say." Not a fan of VIM/EMACS, too. There were instances when redirecting stdout did nothing--had to copy the contents, rm the file, and make it again. Why? Problem on my end?

Some assignments are not very clear with instructions and even a huge jump between assignments. I can only get help from Forum. Sometimes one problem can stop you for several days until someone answer your question in forum.

The programing environment and grading system is pretty hard to use. I would rather write offline in my VSCode and upload my file for check in Coursera. I believe there is way to do so.

This course is very good (and teaches you how to use different tools like gdb and emacs), but was have some bugs with grading.

Well readme's are written with typos - shows how much "care" has been put in to this course by Duke

I​ love the contents, but dealing with unknown test cases is extremely time consuming

External Grader is complicated and slow. Checking test cases is too difficult.

The test cases are tedious and not friendly for people not playing pokers

too hard to code

By Abby V

Here's the thing, if you have experience with coding in other languages, then this is probably a good introduction to c. However, if you are new to programming beware! This is not for you. The instructions for the assignments are often vague which personally led me to a significant amount of unnecessary heartache. Moreover, they don't introduce critical concepts before throwing you at problems that are frankly sometime outside an beginner's scope. If you are new, be prepared for hours of googling in an attempt to figure out the concepts they skimmed over of failed to introduce all together. Also, the final poker testing project costs you hours while you attempt to find invisible bugs with the hints basically begin "well you should try thinking like a programmer"
