Solution to Exercise 1

            "label": "build & run",
            "command": "clang main.c; ./a.exe"

If you are curious why we don’t see 42 as exit code, let me explain:

• each command returns an exit code when it exits

• non-zero (>0) exit codes mean that something went wrong (including 42). Every error code encodes a different error. 42 does not have a particular meaning, I chose it randomly

• we run two commands and the last command exits with an error, then the whole chain exits with the default error code 1.

You can change the returned value to a 0 to test my explanation.
