How newline character formed?

The newline or line-feed character is denoted by ASCII code 0x0A (decimal 10). In C, we use the escape-sequence '\n' to denote a new line. In some cases, particularly where the output is directed to a line printer, a newline is immediately preceded by a carriage return character, 0x0D (13 decimal), which is denoted by the escape sequence '\r' in C. Thus you will often encounter the "\r\n" escape sequence at the end of each line of ASCII text.

Is macro a recursive function?

What is the difference between n and endl in c plus plus?

The \n escape sequence simply inserts a newline within a string. std:endl does the same but also flushes the write buffer.

How does c plus plus code compiled?

When you invoke the compiler, the preprocessor (also known as the precompiler) runs first to process all the precompiler directives and macros; the lines beginning with the pound symbol (#) such as #define and #include. The preprocessor also strips out all of the comments. The preprocessor achieves this by creating one or more temporary, intermediate files containing nothing but C++ code. The compiler then compiles these intermediate files into object code which the linker uses to create the final executable.

When do preprocessor directives execute in c plus plus?

Preprocessing is the first stage of compilation, where macros are expanded, conditional compilation established and code replaced according to the specified directives. The resulting code produces intermediate source files which are then compiled by the main compilation process. Your IDE may include options to retain these intermediate files so you may examine them.
