BASIC is short for Beginner's All-purpose Symbolic Instruction Code and is an easy-to-understand programming language that was popular during 1970 - 1980. Today, BASIC is not used to develop programs, but is sometimes used to help teach the fundamentals of programming. Below is an example of a basic program that prints "Hello World!".
