Comments in C++
In a programming language, comments are either used for explaining code or to prevent execution of code while testing alternate code.
There are two types of comments in C++:
- Single-line Comments
- Multi-line Comments
Single-line Comments
Single-line comments are done by starting the comment with double forward slash //
Example
// This is a comment example
cout << "Hello comment!";
Anything which is after // on the same line will be ignored by the c++ compiler.
Multi-line Comments
Multi-line comments are done by starting the comment with /* and ending with */
Example
/* This is a multi line comment example
This will be ignored by the compiler */
cout << "Hello comment!";
Anything which is between /* */ will be ignored by the C++ compiler.
