Program Code – Unleashing the Power of QBasic: A Comprehensive Guide
REM A QBasic program demonstrating the use of various features such as loops, conditionals, and user input.
CLS
REM Define the maximum Fibonacci sequence value
CONST maxFiboValue = 10000
REM Initialize variables
DIM Fibonacci(100) AS INTEGER
Fibonacci(1) = 1
Fibonacci(2) = 1
REM Calculate Fibonacci series until max value
index = 3
DO WHILE Fibonacci(index – 1) + Fibonacci(index – 2) <= maxFiboValue
Fibonacci(index) = Fibonacci(index – 1) + Fibonacci(index – 2)
index = index + 1
LOOP
REM Display the Fibonacci series
PRINT ‘Fibonacci series up to ‘; maxFiboValue; ‘:’
FOR i = 1 TO index – 1
PRINT Fibonacci(i)
NEXT i
REM Get a number from the user to check if it’s in the Fibonacci series
PRINT ‘Enter a number to check if it’s a Fibonacci number (<=’; maxFiboValue; ‘):’
INPUT userInput
REM Check if the input is a Fibonacci number
found = 0
FOR i = 1 TO index – 1
IF Fibonacci(i) = userInput THEN
found = 1
EXIT FOR
END IF
NEXT i
IF found THEN
PRINT userInput; ‘ is a Fibonacci number.’
ELSE
PRINT userInput; ‘ is not a Fibonacci number.’
END IF
REM End of program
END
Code Output:
The program will first display the Fibonacci series up to the maximum value of 10000, and then prompt the user to enter a number. After the user input, the program will check if the entered number is part of the Fibonacci series and print the result accordingly.
If the user enters ’55’, the expected output would be:
Fibonacci series up to 10000:
1
1
2
3
5
8
13
21
34
55
…
Enter a number to check if it’s a Fibonacci number (<=10000):
55
55 is a Fibonacci number.
Code Explanation:
The program begins by clearing the screen with the ‘CLS’ command. It then defines a constant maxFiboValue that sets the upper limit for the Fibonacci series generation. An array Fibonacci is declared to store the series, and the first two elements are initialized as per the Fibonacci sequence.
A loop then calculates the rest of the Fibonacci series values until reaching the maximum specified by maxFiboValue. This is followed by a loop that prints the calculated Fibonacci numbers to the screen.
Next, the program prompts the user for a number and reads the user input. It uses another loop to compare the user’s input with the values in the Fibonacci series. A variable found is used to indicate if the input is a Fibonacci number. The program responds by informing the user whether their input is or isn’t a Fibonacci number.
Finally, the END statement denotes the termination of the program. This simple yet comprehensive guide demonstrates how to use loops, arrays, conditionals, and user input in QBasic to construct an educational and interactive program.
