             Qbasic stands for "Quick Beginner’s All-Purpose Symbolic Instruction Code". It was

developed by Bill gates and Paul allen but the the real design was made by John G.

kemeny and Thomas E. kurtz at Dartmouth college in 1964. It is a high level

programming language that is understand by computer. It gained popularity in 1990s

and was widely used for teaching programming to beginners due to its simplicity and

ease of use.



As it has basic in its name. IT is the basic language of computer to learn. Nowadays it

is being taught in the schools for students betterment in computer technology and

better use of coding.

 Features of QBASIC:

 1)It is a user friendly language.

 2) It uses simple syntax to write programs.

 3) It provides windows based platforms to write programs.

 4) Debugging can be easily done.

 5) It is a compiler based language.

4) Operators-Operators is a symbol which performs arithmetic(Addition, Subtraction,

 2)Relational operator
