Strings are put together and automatically concatenated into one string;

Add the qualifier R in front of the string or r, which means it is a natural string (nature string), and the format restrictions inside can be ignored;

Add "\" at the end of the physical line to connect to the next physical line ; Brackets, square brackets, and curly brackets can also expand physical lines to a certain extent;
