The preferred way to format source is through Prettier on your local machine. Install Node on your computer, run npm install -g yarn, and then run yarn. To format code, use the yarn prettier command, which will automatically format all .md and .html files. There is also a GitHub Action to format code which can be dispatched manually.Solution: Inspecting the C source, we observe use of gets —always unsafe! We then fire up the debugger via invoke -d dejavu and set a breakpoint at line 8.
