C++ Intro: Livecoding Session

See jfasch/FH-STECE2022 for code.

• Morphing Exercise: Reading A Sensor (Driven By Tests) into something object-oriented, but still C

• Introduce exception handling; this is done to overcome the weird function signature of sensor_get_temperature().

  • Causing exceptions (throw): jfasch/FH-STECE2022

  • Reacting upon exceptions (try, and catch)

    • Production code: jfasch/FH-STECE2022

    • Test code (attention, the logic seems somehow inverted): jfasch/FH-STECE2022
