For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!" In contrast, the equivalent code in C++ [ 7 ] requires the import of the input/output (I/O) software library , the manual declaration of an entry point , and the explicit instruction that the output string should be ...

Original – The first known version "Hello, World!" program by Brian Kernighan from Artsy's Algorythm Auction based on a 1974 Bell Laboratories internal memorandum, "Programming in C: A Tutorial".

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.
For example, Java is not script-like since an application starts at the function named main which need not be at the top of the code. The following code starts at main, then calls printHelloWorld which prints "Hello World".

The C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined.
Here is the entire "Hello, World!" program in Turing with syntax highlighting: put "Hello World!" Turing avoids semicolons and braces, using explicit end markers for most language constructs instead, and allows declarations anywhere. Here is a complete program defining and using the traditional recursive function to calculate a factorial.
