A variable in programming is a storage location identified by a memory address and a symbolic name, holding data that can be modified during program execution. In BASIC, variables are essential for storing and manipulating data, contributing to the language's functionality and versatility.

The PRINT statement in BASIC is used to display text or the value of variables on the screen, facilitating communication between the program and the user. It serves a crucial role in providing output and feedback, enhancing the user's understanding of the program's execution.

The FOR...NEXT loop in BASIC is a control structure that repeats a set of statements for a specified number of iterations, simplifying repetitive tasks and supporting efficient coding. It automates the execution of instructions, reducing the need for redundant code and enhancing program efficiency.

Conditional statements, such as IF...THEN...ELSE, enable decision-making in a program by executing different sets of instructions based on specified conditions. In BASIC, they provide flexibility and control flow, allowing programmers to create dynamic and responsive applications.
