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 ...

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.
Malbolge has three registers, a, c, and d. When a program starts, the value of all three registers is zero. a stands for 'accumulator', set to the value written by all write operations on memory and used for standard I/O. c, the code pointer, is special: it points to the current instruction. [13] d is the data pointer. It is automatically ...

System.out.println(Hello World); The second example would theoretically print the variable Hello World instead of the words "Hello World". A variable in Java cannot have a space in between, so the syntactically correct line would be System.out.println(Hello_World).
BCPL is the language in which the original "Hello, World!" program was written. [6] The first MUD was also written in BCPL . Several operating systems were written partially or wholly in BCPL (for example, TRIPOS and the earliest versions of AmigaDOS). BCPL was also the initial language used in the Xerox PARC Alto project.
