It serves as a compiler directive that suggests (but does not require) that the compiler substitute the body of the function inline by performing inline expansion, i.e. by inserting the function code at the address of each function call, thereby saving the overhead ...
The \n escape sequence allows for shorter code by specifying the newline in the string literal, and for faster runtime by eliminating the text formatting operation. Also, the compiler can map the escape sequence to a character encoding system other than ASCII and thus make the code more portable.

A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
Comments in PHP can be either in C++ style (both inline and block), or use hashes. PHPDoc is a style adapted from Javadoc and is a common standard for documenting PHP code. Starting in PHP 8, the # sign can only mean a comment if it's not immediately followed by '['. Otherwise, it will mean a function attribute, which runs until ']':

In traditional C, there are only /* block comments */. This is only supported by certain Pascal dialects like MIDletPascal. In traditional Pascal, there are { block comments} and (* block comments *). Modern Pascal, like Object Pascal (Delphi, FPC), as well as modern C implementations allow C++ style comments // line comments
