Qbasic Program; Write a program to find the simple interest.

Question:- Write a program to find the sum of any two integers.

Solution:-

Before starting a Qbasic program you need to know what a program is. So I'm going to tell you a little bit about the program and so on.

Computer Program:-

A computer Program is a set of instructions given to the computer to perform a particular task. It is writtern in a programming language such as QBASIC, C, C++ etc. given by the users that are translated into machine level language to obtain the desired result.

Computer Programming:-

Computer Programming is the process of designing, writing, testing, debugging and maintaining the source code written in a particular computer language.

Programmer:-

A programmer is a person who is involved in the different processes of computer programming.

Programming Language:-

It is coded or artificial language used to write instructions that a computer can understand to do what the user wants.

A programming langage is therefore a practical way for us to give instructions to a computer.

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.
• The syntaxes of the statements are checked 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.

Downloading QBASIC Software:-

In Windows 7, 8, 10:-

I have written a post before this. In this post, I have provided detailed experimental information on how to download and run Qbasic software on your computer.

You can find out how to download Qbasic by looking at this post. After downloading Qbasic you should run Application file.

Click on Link: CLICK HERE TO DOWNLOAD QBASIC SOFTWARE

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.

Your First Program:-

Just type the below statements in the above screen.

PRINT "Hello World"

END

Running (executing) your program:-

Press F5 button from your computer keyboard. Now you will see the output screen as below.

This is a sample program to display the words "Hello World" on the output screen.

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 To find out the simple interest

Cls

P = 1000

T = 2

R = 6

I = P * T * R / 100

Print "The Simple Interest is = "; I

End

Before we go on Syntax we know some below topics:-

QBASIC Statements:-

The instructions within a program are called statements. Each QBasic instruction is like a sentence. As a sentence must have a verb in it, each Qbasic instruction must have a Qbasic Keyword. A Qbasic statement is either executable or non-executable.

Now In the above Syntax the following statements are used:-

CLS:-

To clear the screen

REM Statements [Comments]:-

Commensts may be included in a QBASIC Program to describe the purpose or to clarify some portion of code in a program. In QBasic, we use REM or ' for comments.

Print Statement (Print):-

To display the output on the screen.

END Statement:-

It is a declaration that ends a QBASIC program, procedure or block.

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 output screen is display.

Step 5:- After running program, the simple interest calculates and display on the output screen. 

That's all.

Step 7:- 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 8:- 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 9:- Your File saved. If you need to edit in your code, you can open your saved file later.
