BASIC:
BASIC stands for Beginners All purpose Symbolic Instruction Code. BASIC is a high level programming language. As its name shows, it is designed especially for beginners. BASIC was developed in 1964 by John Kemeny and Thomas Kurtz at Darmouth College in New Hampshire. It is very important and useful for beginners who are in programming field. BASIC is also useful for some high-ended programming.
GW-BASIC:
GW-BASIC Stands for General Work Beginners All purpose Symbolic Instruction Code. It is an Interpreter (Language Translator) for BASIC language. GW-BASIC is one of the most solid and popular Interpreter for BASIC language. It was developed my Microsoft in 1983.
Programs of BASIC Language:
