C++ - Programming Language

This course covers the basics of programming in C++.

In C++, comments are used to add explanations, descriptions or notes to the code, which are ignored by the compiler and not executed. They can be used to make the code more readable and easier to understand for other developers who may need to work with or modify the code in the future.

There are two types of comments in C++: single-line comments and multi-line comments.

Single-line comments start with two forward slashes //, and continue until the end of the line:

// This is a single-line comment
int x = 10; // This is also a single-line comment

Multi-line comments start with /* and end with */, and can span multiple lines:

/* This is a
   multi-line
   comment */
int y = 20; /* This is also a
               multi-line comment */

It’s important to note that comments should be used judiciously and effectively. They can be helpful for explaining complex code or documenting APIs, but too many comments or poorly written comments can clutter the code and make it harder to read. It’s also a good practice to update comments whenever the code changes, to ensure that they remain accurate and relevant.
