Lecture Summary: Comments in C++

Introduction

• Objective: Understanding comments in C++.
• Purpose of Comments:
  • Explain Code: Describe what the code is doing.
  • Explain Approach: Justify why a particular approach was taken.

Benefits of Comments

• Make code more readable and understandable for future developers.
• Aid in collaboration and maintenance.

Types of Comments in C++

1. Single Line Comments

   • Format: // comment
   • Shortcut: Ctrl + / on Windows or Cmd + / on Mac.
   • Use Cases:
     • Describe a specific line of code to enhance clarity.
     • Comment a line out to test a new version without deleting original code.

2. Multi-Line Comments

   • Format: /* comment */
   • Shortcut: Ctrl + Shift + / on Windows or Cmd + Shift + / on Mac.
   • Use Cases:
     • Comment out a block of code.
     • Explain more detailed information over multiple lines.
   • Best Practices:
     • Avoid commenting obvious code.
     • Prioritize explaining the reasons behind the code rather than its functionality.

Conclusion

• Comments are a crucial part of programming, aiding in code understanding and collaboration.
• Well-placed comments improve code readability and help convey the rationale behind decisions in the code.
