Study Notes
Start with the definition and purpose of the concept. Learn the basic syntax, identify the role of each part of a program, then compile a small example and experiment with different inputs.
Good programming habits
- Use meaningful variable and function names.
- Indent code consistently.
- Compile frequently so errors are easier to locate.
- Test normal, boundary and unexpected inputs.
- Write comments where they explain intent rather than obvious syntax.
Practice method
After reading this topic, close the notes and reproduce a small program from memory. Change one requirement, test the result and explain why the output changes.
