Understanding QBASIC Programming Language

Before we dive into creating our program, it's important to understand the basics of QBASIC programming language. QBASIC is a high-level programming language that was developed by Microsoft for use with their DOS operating system. QBASIC uses simple and easy-to-understand syntax, making it a popular choice for beginners.

Coding for QBASIC program to display the average of input two numbers

CLS

INPUT "Enter first number:"; x

INPUT "Enter second number:"; y

p = (x + y) / 2

PRINT "Average of two numbers="; p

END

Explanation:

1. The program begins with the CLS command, which clears the screen.
2. The next two lines prompt the user to enter two numbers using the INPUT command. The first number is stored in the variable x and the second number is stored in the variable y.
3. The program then calculates the average of the two numbers using the formula p = (x + y) / 2, and stores the result in the variable p.
4. The final line uses the PRINT command to display the calculated average to the user.
5. The program then ends with the END command.

We can write the above program by using SUB and FUNCTION Procedures

By using SUB procedure (SUB..END SUB)

DECLARE SUB average (x, y)

CLS

INPUT "Enter first number:"; x

INPUT "Enter second number:"; y

CALL average(x, y)

END

 

SUB average (x, y)

p = (x + y) / 2

PRINT "Average of two numbers="; p

END SUB

 

By using FUNCTION procedure (FUNCTION…END FUNCTION)

DECLARE FUNCTION average (x, y)

CLS

INPUT "Enter first number:"; x

INPUT "Enter second number:"; y

PRINT "Average of two numbers="; average(x, y)

END

 

FUNCTION average (x, y)

average = (x + y) / 2

END FUNCTION
