Comments are fine, as long as they are used only when necessary and they explain something that is not obvious. The examples of mattnz make that clear. There is nothing that is not obvious in that part of the code since it is just using already documented features. Thus for example by executing man strncpy you can find out everything about this function. Not putting any comments in such code is much better and less confusing for other programmers.

Document only the complex parts of your code, and if necessary the input/output and arguments of your functions/methods; the latter is useful if you want to export your API using a documentation system. Do not forget that when a part of the code is updated, the comments must also be updated, thus the maintenance time is much longer; which means that your comments should really worth the effort.
