Now we are going to discuss what are C++ Comments. If you have some little knowledge about Python or C# you could also go through my article about comments of both languages so it might be helpful for you, Now lets discuss C++ Comments.

C++ Comments

Comments can be used to explain C++ code or the source code that we have written in our IDE , and to make it more readable. It can also be used to prevent execution when testing alternative code.

Types of Comments

The syntax for adding comments varies between programming languages. However, there are two main types of comments.

1-Single Line Comments

Single-line comments start with two forward slashes (//). Any text between // and the end of the line is ignored by C++ compiler (will not be executed).

An example of single line comment is below

// This is a comment
cout << "Hello World!";

Output with Single line comment

Hello World!

2-Multi Line Comments

Multi-line comments start with /* and end with */. Any text between /* and */ will be ignored by C# compiler.

An example of Multi Line comment is below

/* The code below will print the words Hello World!
to the screen, and it is amazing */
cout << "Hello World!";

Output with Multi line comment

Hello World!

Conclusion

In conclusion, comments play a crucial role in programming as valuable companions to the code. They provide a means for programmers to explain the intricacies of their creations, making the codebase more understandable and maintainable. By adding comments, developers can leave behind a trail of insights detailing their thought processes and decision-making, which proves invaluable for themselves and future project contributors. The ability to disable code temporarily during debugging and the support for version control annotations further enhance the significance of comments. As you embark on your coding journey, remember that thoughtful and clear comments are a testament to your programming prowess and commitment to building elegant and understandable solutions.
