What is the purpose of the INPUT statement in BASIC?
Displaying text on the screen
Repeating a set of statements
Redirecting program flow
Receiving input from the user
Which BASIC operation allows the program to repeat a set of statements for a specified number of iterations?
IF...THEN...ELSE Statement
GOTO Statement
FOR...NEXT Loop
FUNCTION Operation
What type of control structure does the IF...THEN...ELSE statement represent in BASIC?
Loop
Function
Conditional
Input
Which BASIC statement is often discouraged in modern programming practices due to its potential impact on code complexity?

Describe the role of a variable in programming and its significance in BASIC.
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.
Explain the function of the PRINT statement in BASIC and its importance in program-user communication.
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.
Discuss the purpose of the FOR...NEXT loop in BASIC and how it simplifies coding for repetitive tasks.
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.
Examine the role of conditional statements, specifically IF...THEN...ELSE, in programming and how they contribute to decision-making in a BASIC program.
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.
