Hello World!!!

A simple statement which gives a programmer confidence that the setup of compilers and tools is working.

Itself it seems to be a very insignificant thing, but without this, no one has ever started programming.

So let's do Hello World in multiple languages starting with A and ending with Z (because why not 😊)

A

Ada - A language which appeared in 1980 and is still running many of our mission critical application like avionics, air traffic control, railways, banking, military and space technology.
Named after after Lady Ada Lovelace, who is often regarded as the first computer programmer.

with Ada.Text_IO; use Ada.Text_IO;
procedure Hello is
begin
    Put_Line ("Hello, world!");
end Hello;

AWK - A language typically designed for text processing. Used primarily for data extraction and reporting. A standard tool in may *nix distros.
Named after Alfred Aho (Bell Labs, Aho Ulman Compiler Design is a staple in Computer Science Courses), Peter Weinberger (Bell Labs, Google, FORTRAN compiler etc.) and Brian Kernighan (Bell Labs, Unix and The C Programming Language etc.).

BEGIN { print "Hello, world!" }

B

BASIC - Created by Kemeny and Kurtz from Dartmouth College, it was popularized when Bill Gates, Paul Allen and Monte Davidoff ported it to microcomputers (newly formed Microsoft). BASIC was one of the few languages that was both high-level enough to be usable by those without training and small enough to fit into the microcomputers of the day, making it the de facto standard programming language on early microcomputers.
BASIC is an acronym for Beginners All Purpose Symbolic Instruction Code.

10 PRINT "Hello, World!"
20 END

BrainFuck - Created by Urban Müller, it is an esoteric programming language which only has eight commands. Esoteric languages are languages designed to test the boundaries of computer programming language design or as proof of concept.

C

C - Originally developed by Dennis Ritchie in 1972 - 73 as a successor to B at Bell Labs. It was created to develop utilities for Unix operating system and then later to create the Unix kernel itself. It is one of the most widespread languages in use till date and is ranked number 1 in TIOBE index of programming language (June 2021). Most of us cut our programming teeth on this beauty.

#include <stdio.h>

int main(void)
{
    printf("hello, world\n");
}

COBOL - A language which is designed for business use case. Designed in 1959 by CODASYL it is a verbose language with English like syntax. Influenced by Flow-Matic which was originally created by Rear Admiral Grace Hopper, this language was and is still widely used in mainframe computers. Even now big financial institutions are using COBOL running on mainframes.
COBOL is an acronym for Common Business Oriented Language.
