Fundamentals of QBASIC: A Programming Language

Answer

QBASIC stands for Quick Beginner’s All-purpose Symbolic Instruction Code. It is a high-level programming language developed by Bill Gates and Paul Allen in 1975 to replace GW-BASIC. It is user-friendl…

Answer

QBASIC is beginner-friendly because it has simple syntax, does not require line numbers, provides error detection, and supports both numeric and string data. It also allows users to write, run, and de…

Answer

The four main elements of QBASIC are: 1) Character Sets, 2) Operators and Expressions, 3) Constants and Variables, and 4) Commands and Statements. These are essential for writing any QBASIC program.

Answer

A character set in QBASIC refers to the collection of symbols used to write programs. It includes alphabets (A-Z, a-z), numbers (0-9), and special characters like +, -, *, /, $, etc. These are used to…

Answer

Three examples of special characters used in QBASIC are: 1) * (asterisk) for multiplication, 2) / (slash) for division, and 3) $ (dollar sign) used at the end of string variable names like A$.

Answer

An operator in QBASIC is a symbol that performs an operation on data (operands). For example, + adds two numbers, > checks if one value is greater than another. Operators are used to build expressions…

Answer

The three types of operators in QBASIC are: 1) Arithmetical Operators (like +, -, *), 2) Relational Operators (like <, >, =), and 3) Logical Operators (like AND, OR, NOT). Each type is used for differ…

Answer

The result is 11. QBASIC follows the BODMAS rule (Brackets, Orders, Division/Multiplication, Addition/Subtraction). So, multiplication is done first: 3 * 2 = 6, then 5 + 6 = 11.
