main {printf ("hello, world");} In the above example, the main( ) function defines where the program should start executing . The function body consists of a single statement , a call to the printf() function, which stands for " print f ormatted"; it outputs to the console whatever is passed to it as the parameter , in this case the string ...
The "Hello world" program uses printf in its simplest form: by simply passing it a string with no special formatting codes, and no extra arguments. The input text is simply printed to the screen. (Note that the "\n" special escape sequence is converted into a newline character.)
The next line of the program is a statement that calls (i.e. diverts execution to) a function named printf, which in this case is supplied from a system library. In this call, the printf function is passed (i.e. provided with) a single argument, which is the address of the first character in the string literal "hello, world\n".

printf is a C standard library function that formats text and writes it to standard output. The name, printf is short for print formatted where print refers to output to a printer although the functions are not limited to printer output.

#include <stdio.h> int main (void) {printf ("Hello, World! \n "); return 0;} In this case, the file name is enclosed in angle brackets to denote that it is a system file. For a file in the codebase being built , double-quotes are used instead.
The following command prints the text Hello World on the standard output stream, which, in this case, just prints the text on the screen. The program name is echo and the argument is "Hello World". The quotes are used to prevent Hello and World being treated as separate tokens: echo "Hello World" The following commands are equivalent.
