Qbasic Program; Write a program to check the numbers between 1 & 3.

Question:- Write a program to check the numbers between 1 & 3.

Solution:-

Before going on code, i will you introduce about Qbasic Programming.

QBASIC (Quick Beginner's All purpose Symbolic Instruction Code) is a high level programming language delveloped by Microsoft Corporation in 1985. It is a modular Programming Language, where program is divided into different modules or procedure. QBasic is simple and easy to learn. It uses English like Keywords and mathematical symbols to write a program.

Features of QBasic Programming:-

• It is simple and easy to learn
• It is an interpreter having its own editor.
• It has dynamic program debugging.
• It supports the local and global variable.
• It supports modular programming.
• It capitalizes the reserved words automatically.

Starting QBASIC

QBASIC may not be on your computer. At first, you need to have QBASIC in your computer. It is freely available. You can download it from internet as well.

If there is any problem, please comment in the comment box below..

Now you will see the QBASIC window where you have to write QBASIC Statements to make your program. 

Please if the following Images do not clearly displays, click on images to view largely images.

Now we will start write code for the above query.

QBASIC CODE for above Question:- 

Step 1:- Open Qbasic Software from your computer.

Step 2:- The following Qbasic Code is used to solve to above query. Write down the following Qbasic Code clearly in the Qbasic software that you have opened.

Rem Write a program to check the numbers between 1 & 3.

Cls

Input "Enter the numbers between 1 to 3"; N

Select Case N

    Case 1

        Print "The number you have typed is 1";

    Case 2

        Print "The number you have typed is 2";

    Case 3

        Print "The number you have typed is 3";

    Case Else

        Print "It’s out of range";

End Select

End

In the above Syntax:-

CLS:-

To clear the screen

Input Statement (Input):-
Input Statements are used to supply the data during the execution of the program from the keyboard. 

SELECT CASE Statement:-

Purpose:- To execute one of several statement blocks depending on the value of an expression.

Syntax:

SELECT CASE expression

CASE expressionlist1

[Statementblock1]

CASE expressionlist2

[Statementblock2]

CASE ELSE

[Statementblockn]

END SELECT

- expression is any numeric or string expression.

- expressionlist contains one or more expressions of the same type as expression

-  The IS keyword must precede any relational operators in a expression

- expression TO expression - for range

END SELECT:- It terminates the SELECT CASE Statement.

Print Statement (Print):-

To display the output on the screen.

END:-

It terminates your program.

After typing the above code in Qbasic Software, you have to follow following steps.

Step 3:- To run this program, Go to Run Tab menu, click to start. You can also press Shortcut F5 key from the keyboard.

After this, click on OK button.

Step 4:- After running the program, following black window is display.

The number you have entered whether it is between 1 to 3 displays on the screen. That's all.

Step 6:- But don't forget to save the program you have written. To save press ctrl + s key or Go to File Menu, Click on Save button.

Step 7:- Write the name of file in the file name field, Choose the file path where you want to save the file in the computer and Click on OK button.

Step 8:- Your File saved. If you need to edit in your code, you can open your saved file later.
