A comment is a piece of text within a program that is not executed. It can be used to provide additional information to aid in understanding the code.
Single-line comments are created using two consecutive forward slashes. The compiler ignores any text after

// This line will denote a comment in C++
Multi-line comments are created using

*/ to end the comment. The compiler ignores any text in between.
/*This is all commented out.None of it is going to run!*/
