Introduction to Computer Programming: Debugging and Development Strategies

In Lecture 8 of CS 126, Zeke Maier covers critical aspects of computer programming, including queries and essential administrivia. The session highlights AD Exercises 4.2 and 4.3, focusing on techniques for effective development and debugging. Students learn to write methods, compile code, and fix both syntax and semantic errors. The importance of identifying error types, especially compiler errors, is emphasized, along with useful debugging strategies. Additional resources like lab demos and quiz solutions are also discussed to support ongoing learning.
