Checking math exercises can be easily done in a automated way, by using GitHub Classroom together with GNU Octave. We have recently discussed how to autograde C++ programming exercises, and now we extend this knowledge for math exercises. …

The Bazel Build system was originated from Google, being released afterward to the general public as open-source. It is important for languages such as C/C++ that depend on compile/linking phases, which often depend on other third-party projects/libraries. …

Autograding tools are very important to improve feedback during programming exercises for students. Hopefully, we already have amazing (and free) tools/platforms to do that! Let’s take a look at Github Classroom for autograding C++ tests using Catch2. If you want to start learning on practice, just click follow this link…
