Single-Line Comments in C++
In C++, single-line comments are created using the double forward slash symbol "//". This allows programmers to annotate their code with explanations or notes without affecting the execution of the program.
How Single-Line Comments Work
- Syntax: Any text following the "//" on the same line is treated as a comment.
- Purpose:
- To clarify complex code sections.
- To temporarily disable code during debugging.
- To provide context or information for other developers.
Examples of Single-Line Comments
- A simple comment:
cpp
// This is a single-line comment
- Commenting out code:
cpp
int x = 10; // Initialize x to 10
// int y = 20; // This line is commented out
Other Comment Types in C++
- Multi-Line Comments: These use the syntax "/* comment text */". They can span multiple lines but are not suitable for single-line usage.
- Preprocessor Directives: The symbol "#" is used for preprocessor commands, not for comments.
Conclusion
The correct answer to the question about single-line comments in C++ is option 'A' "//". It is an essential feature that helps maintain code clarity and organization. By using single-line comments effectively, programmers can enhance the readability and maintainability of their code.
