QBASIC

 QBASIC, short for "Quick Beginner’s All-Purpose Symbolic Instruction Code," was crafted by Bill Gates and Paul Allen, with the initial design originating from John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1964. Functioning as a high-level programming language, it holds the capability to be comprehended by computers. Its surge in popularity during the 1990s resulted from its inherent simplicity and user-friendly nature, making it a prominent choice for teaching programming to novices.

Given its nomenclature, QBASIC is indeed the fundamental language for computer learning. Presently, educational institutions incorporate it into their curriculum, aiming to empower students in computer technology and enhance their coding proficiency.

Key Features of QBASIC:

1) User-friendliness characterizes QBASIC as a language.

2) The utilization of straightforward syntax simplifies program writing.

3) Windows-based platforms are provided for program development.

4) Debugging is conveniently achievable.

5) It operates as a compiler-based language.

Character Sets in QBASIC encompass alphabets, numbers, and special symbols permitted within the language. Noteworthy distinctions exist within types:

1) Alphabets: Both capital (A to Z) and lowercase (a to z) letters are permissible for commands and statements. However, data entries mandate exclusive use of uppercase letters (e.g., "CLS," "Td," "Ram").

2) Numbers: The entire numerical spectrum, from 0 to 9, is accepted.

3) Special Symbols: QBASIC embraces specific symbols like "!", "@," "#," "&," and others.

4) Operators: Employed for arithmetic (addition, subtraction, multiplication, division) and logical (comparison) operations, operators can be classified into three types:

   a) Arithmetical operators

   b) Relational operators

   c) Logical operators
