Year 11 D QBASIC

What is the purpose of variables in QBASIC?

• The purpose of variables in QBASIC is to store and manipulate data during program execution.

• Variables in QBASIC are meant to confuse the programmer.

• Variables in QBASIC are used for decorative purposes only.

• Variables in QBASIC are unnecessary and should be avoided.

What are the different data types supported in QBASIC?

• Float

• Integer, Single, Double, String, Boolean

• Character

• Array

How can you display output in QBASIC?

• Use the PRINT statement in QBASIC.

• Use the SING statement in QBASIC.

• Implement the YELL statement in QBASIC.

• Utilize the DANCE statement in QBASIC.

Explain the INPUT statement in QBASIC.

• The INPUT statement in QBASIC is used to create loops.

• The INPUT statement in QBASIC is used to receive input from the user during program execution.

• The INPUT statement in QBASIC is used to perform mathematical calculations.

• The INPUT statement in QBASIC is used to display output on the screen.

What is the syntax for IF-THEN-ELSE statement in QBASIC?

• IF condition THEN statement2 ELSE statement1

• IF condition THEN statement1 ELSE statement2

• IF condition THEN statement1 ELSEIF statement2

• IF condition THEN statement1 ELSE statement2

How do you use the SELECT CASE statement in QBASIC?

• SELECT CASE expression, CASE value1: statements, CASE value2: statements, ..., CASE ELSE: statements, END SELECT

• SELECT CASE expression, CASE value1: statements, CASE value2: statements, ..., CASE DEFAULT: statements, END SELECT

• SELECT CASE expression, CASE value1: statements, CASE value2: statements, ..., CASE ELSE: statements, END IF

• SELECT CASE expression, CASE value1: statements, CASE value2: statements, ..., CASE OTHERWISE: statements, END SELECT

What is the purpose of loops in QBASIC?

• Loops in QBASIC are used to create animations

• Loops in QBASIC are designed to print text on the screen

• Loops in QBASIC are meant to play sound effects

• The purpose of loops in QBASIC is to repeat a block of code multiple times until a certain condition is met.

Differentiate between FOR-NEXT and DO LOOP in QBASIC.

• FOR-NEXT loop is used for indefinite iteration based on a condition

• DO LOOP is used for definite iteration based on specified initial and final values

• FOR-NEXT loop is used in QBASIC, while DO LOOP is used in C++

• The main difference between FOR-NEXT and DO LOOP in QBASIC is that FOR-NEXT loop is used for definite iteration based on specified initial and final values, while DO loop is used for indefinite iteration based on a condition.

Explain the WHILE-WEND loop in QBASIC.

• WEND loop in QBASIC is similar to FOR loop

• The WHILE-WEND loop in QBASIC is structured as follows: WHILE condition ' Code block to be executed while the condition is true WEND

• The WHILE loop in QBASIC is used for iteration

• QBASIC does not support WHILE-WEND loop

How can you exit a loop prematurely in QBASIC?

• BREAK

• STOP

• EXIT DO or EXIT FOR

• END
