program. A "Hello, World!" program is generally a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!". A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. A "Hello, World!"
program, which does nothing but issue the message "Hello, World!" to the user (such as by displaying it on a screen). It has been used since the earliest programs, and in many computer languages. This tradition was further popularised after being printed in an introductory chapter of the book The C Programming Language by Kernighan & Ritchie. [29]
Program code is in blue. In computer programming, a comment is a programmer-readable explanation or annotation in the source code of a computer program. They are added with the purpose of making the source code easier for humans to understand, and are generally ignored by compilers and interpreters. [1][2] The syntax of comments in various ...
It is also called sharp-exclamation, sha-bang, [1] [2] hashbang, [3] [4] pound-bang, [5] [6] or hash-pling. [7] When a text file with a shebang is used as if it were an executable in a Unix-like operating system, the program loader mechanism parses the rest of the file's initial line as an interpreter directive.
Languages that interpret the end of line to be the end of a statement are called "line-oriented" languages. "Line continuation" is a convention in line-oriented languages where the newline character could potentially be misinterpreted as a statement terminator. In such languages, it allows a single statement to span more than just one line.

Go (programming language) Go is a statically typed, compiled high-level programming language designed at Google [12] by Robert Griesemer, Rob Pike, and Ken Thompson. [4] It is syntactically similar to C, but also has memory safety, garbage collection, structural typing, [7] and CSP -style concurrency. [13]
In computer programming, the symbol "?" has a special meaning in many programming languages. In C-descended languages, ? is part of the ?: operator, which is used to evaluate simple boolean conditions. In C# 2.0, the ? modifier is used to handle nullable data types and ?? is the null coalescing operator.
