how to writte comment in c++

To write a comment in C++, you can use the double forward slash "//" followed by your comment. Here is a step-by-step explanation:

  1. Open your C++ source code file using a text editor or an integrated development environment (IDE).

  2. Locate the line of code where you want to add a comment.

  3. To add a single-line comment, simply type "//" (without the quotes) followed by your comment. For example:

// This is a single-line comment
  1. To add a multi-line comment, you can use the forward slash followed by an asterisk "/" at the beginning of the comment block, and the asterisk followed by the forward slash "/" at the end of the comment block. For example:
/*
This is a multi-line comment.
It can span across multiple lines.
*/
  1. Make sure to provide clear and concise explanations in your comments to improve code readability and maintainability.

Remember, comments are not executed by the compiler or interpreter and are solely meant for human understanding. They are useful for providing context, explaining complex code segments, or making notes for future reference.
