Dec 5, 2009 · In general, comments should be dealt with in a similar manner to code separation -- interface-related comments (such as your example) would go in the header, whereas implementation-related comments would be better suited for the .cpp file.

I'm programming in C++ using Visual Studio 2010 Ultimate. I want to document some functions and I want the documentation to show up in Intellisense. According to MSDN, I just need to put the comment before the declaration or after it on the same line. So I tried this: // This is a test.

C++ Comments. Comments can be used to explain C++ code, and to make it more readable. It can also be used to prevent execution when testing alternative code. Comments can be singled-lined or multi-lined.

Mar 10, 2025 · Comments in C++ are meant to explain the code as well as to make it more readable. Their purpose is to provide information about code lines. When testing alternative code, they can also be used to prevent execution of some part of the code.

May 28, 2024 · Comments serve as a sort of in-code documentation. When inserted into a program, they are effectively ignored by the compiler; they are solely intended to be used as notes by the humans that read source code.

In C++, you can add a reference to a function in comments by using the `&` operator to indicate that the function argument is passed by reference, allowing modifications to the original argument. // Function that takes an integer by reference void increment(int &value) { value++; }

In this tutorial, you'll learn how you write comments in C++. You'll learn both the technical aspects of including comments in your code as well as professional guidelines on what types of comments you should include (and avoid). You can skip to a specific section of this tutorial on how to write C++ comments using the table of contents below: 1.

Declaration comments describe use of the function; comments at the definition of a function describe operation. Every function declaration should have comments immediately preceding it that describe what the function does and how to use it.

To add a function in C++ comments, you can use single-line comments (`//`) or multi-line comments (`/* ... */`) to describe the function's purpose and usage without impacting the code execution. Here's a code snippet demonstrating both comment types:

Dec 23, 2021 · Here are some rules to help you achieve a happy medium: Rule 1: Comments should not duplicate the code. Rule 2: Good comments do not excuse unclear code. Rule 3: If you can't write a clear comment, there may be a problem with the code. Rule 4: Comments should dispel confusion, not cause it. Rule 5: Explain unidiomatic code in comments.
