QBASIC Programming

QBASIC Programming

A computer is a useful device that can process data and produce the meaningful output. However, computer is just a machine and to get the desired output, it must be instructed to do so. A set of instructions given to the computer is called a program.

BASIC is a programming language, BASIC stands for Beginners' All Purpose Symbolic Instruction Code. It is very popular because of its simplicity. It is best suited for beginners. It was developed in 1964 at Dartmouth College, U.S.A. by Professor John Kemeny and Thomas Kurtz. It allows the usage of simple English like statements and mathematical operators. There are various versions of BASIC like TURBO BASIC, and QBASIC.

Like all high level language programming language, QBASIC also works in an Integrated Development environment (IDE) that includes a language editor,  language translator and a debugger apart from the QBASIC language itself.

In the QBASIC Integrated Development Environment (IDE):

Your write programs to make a computer do a particular task using the QBASIC programming language. The program that you write is also known as the source code.

The screen on which you write QBASIC program is called the QBASIC editor. It gives you facilities to type and edit programs.

QBASIC IDE has an inbuilt language translator (Interpreter). It converts the program into the binary language or the machine language (the language of 0's and 1's), so that the CPU can understand the programs/instructions and carry out the given task.
