Introduction to BASIC Programming Language - JSS2 Computer Studies Lesson Note

BASIC, which stands for Beginner's All-purpose Symbolic Instruction Code, is a high-level programming language designed for beginners and simplicity. Developed in the mid-1960s, BASIC gained popularity due to its easy-to-understand syntax and accessibility. Originally used for educational purposes, BASIC became a widely used language for various applications, including early personal computers. Common programming terms include:

Variable: A variable is a storage location identified by a memory address and a symbolic name. It holds data that can be modified during program execution.

Statement: In programming, a statement is a single line of code that performs a specific action or operation. BASIC, like many programming languages, relies on statements to express the logic of a program.

Loop: A loop is a control structure that allows the repeated execution of a set of statements. It is used to automate tasks or iterate over a sequence of instructions.

Conditionals: Conditional statements, such as "IF...THEN...ELSE," enable the execution of different code blocks based on specified conditions. They provide decision-making capabilities in a program.

Function: A function is a named block of code that performs a specific task or operation. Functions enhance code modularity and reusability.
