C++ comments

In C++, comments are used to add explanations or annotations to code that are not executed by the compiler. There are two types of comments in C++:

Single-line comments: Single-line comments start with // and continue until the end of the line. They are often used to add brief explanations or to disable a line of code.

For example:

				
					// This is a single-line comment
int x = 10;  // This line sets the value of x to 10

Multi-line comments: Multi-line comments start with /* and end with */. They can span multiple lines and are often used to add detailed explanations or to disable a block of code.

For example:

				
					/*
This is a multi-line comment that spans
multiple lines. It can be used to add detailed
explanations or to disable a block of code.
*/
int y = 20;  /* This line sets the value of y to 20 */

Comments are a useful tool for documenting code and making it easier to understand and maintain. However, it’s important to use them judiciously and not over-comment code, as this can make it harder to read and follow the logic of the program.
