About Qbasic and its stuff
Introduction
QBasic is an integrated development environment and interpreter for a variety of dialects of BASIC which are based on QuickBASIC. Code entered into the IDE is compiled to an intermediate representation, and this IR is immediately executed on demand within the IDE. It stands for "Quick Beginner’s All-Purpose Symbolic Instruction Code". IT was developed by Bill gates and Paul allen but the actual real design was made by John G. kemeny and Thomas E. kutz at Dartmouth college in 1964. Qbasic is a high level language. It began to gain its popularity in 1990s and was used around the world to teach programming to beginners due to its simplicity and easy to use. The statements of QBASIC are like English words and meanings of those statements. It converts one statement of a program into machine codes at a time.
Features of Qbasic
- Simple and easy to learn the language
- Applicable for use in Business purposes and Mathematical learnings
- Available in every computer from micro to mainframe
- QBASIC has a lot fewer requirements
- Debugging can be easily done
- It checks syntax automatically
thINGS TO KNOW
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
