3.13 LINE SPLICING

We are aware that C++ allows us to write programs in an unformatted manner. A program line can contain many expressions or a single expression can be written in many lines.

When the string we are writing cannot be completed in one line, a back slash (\) is inserted as the last character and the string is continued in the next line. In this way, a single string can be written by us and understood by the compiler, which spans many lines. For example:
