ABC is a programming language created in 1980 by Dr. William Cook and Charles Simonyi. It was designed to be a simple, easy to learn language that would allow beginners to create programs quickly. ABC has a small set of keywords and a simple syntax. It is not case sensitive and does not require semicolons or curly braces.
ABC programs are made up of a series of commands. Each command is executed in order from top to bottom. The language supports variables, input/output, and basic math and logic operations. It also has a few built-in functions for things like generating random numbers and converting data types.
Despite its simplicity, ABC is a powerful language. It has been used to create everything from small utility programs to large scale enterprise applications.
