**QBasic programming examples** and exercises for class 6 and class 7 standard.

Qbasic sample example programs for beginners. In this article, we will see some **QBasic programming examples** and some simple exercises to understand how it works.

These **Qbasic program examples** are a beginner-level, which mostly will help you to understand the concept of a variable and some basic qbasic statements like PRINT, INPUT, CLS etc.

Here are some Qbasic commands along with the descriptions that will be used in this article.

Before getting started it is important to know the basic Qbasic statements or QBasic commands first. If you have not read about it, check: – **QBasic Commands and Statements-2020**

Here, we will code some simple examples which are easy to understand for class 6/ class 7 students, who have started with **QBasic programming.**

Here, the program codes are explained with there formulas to help you understand better.

**EXAMPLE 1:**

`CLS`

`INPUT ‘Enter your name’;n$`

`PRINT ‘The name is’;n$`

`END`

Here since the input data is a string then the variable name ( n ) in which it is to be stored is written after INPUT command followed by $ sign( n$ ).

**EXAMPLE 2:**

`CLS`

`INPUT ” Enter the name “;N$`

`INPUT ” Enter the city”;C$`

`INPUT ” Enter the country”;CO$`

`INPUT ” Enter the age”;A`

`PRINT ” The name is “;N$`

`PRINT ” The city is “;C$`

`PRINT ” The country is “;CO$`

`PRINT ” The age is “;A`

`EN`

D

Here name, city, country are string so its variable name is written with sign **$** before it and since age is a number so the variable name is written directly.

**Example 3:**

FORMULA:Area of a Rectangle is length x breadth. Here length is variableland breadth is variableb. And is the variable to store the value of the result and print it as output.

`CLS`

`INPUT ” Enter the length ” ;l`

`INPUT ” Enter the breadth ” ;b`

`LET A = l*b`

`PRINT” The area of rectangle=” ;a`

`END`

**Example 4:**

FORMULA:Area of triangle is ½ x base x height.

Here in this program we that variable **b** as base and **h** as height. T is the variable to store the result and print it.

`CLS`

`INPUT ” Enter the base” ;b`

`INPUT ” Enter the height” ;h`

`LET T = 1/2*b*h`

`PRINT” The area of triangle=” ;T`

`END`

**Example 5:**

FORMULA: Area of a circle is 22/7 x radius^2. Here we use variableRas Radius. AndCis the variable where we store the result.

`CLS`

`INPUT” Enter the radius ” ;R`

`LET C=22/7*R^2`

`PRINT ” The area of circle =” ;C`

`END`

**Example 6:**

FORMULA:Area of a square is = Side2 square units. Here the result is stored in variable “square”.

`CLS`

`INPUT” Enter the number” ;n`

`LET square= n^2`

`PRINT” The area of square=” ;Square`

`END`

**Example 7:**

FORMULA: Area of a box = length x breadth x height.

The variable are **l**, **b** , and **h** for length, breadth and height and the result will be stored in the variable **volume**.

`CLS`

`INPUT ” Enter the length ” ;l`

`INPUT ” Enter the breadth ” ;b`

`INPUT ” Enter the height ” ;h`

`LET volume= l*b*h`

`PRINT” The volume of box =” ;volume`

`END`

**Example 8:**

FORMULA: circumference = 22/7 x Radius x 2

`CLS`

`INPUT” Enter the radius ” ;R`

`LET Circumference=22/7*R*2`

`PRINT ” The area of circle =” ;Circumference`

`END`

**Example 9:**

FORMULA : Simple Interest = Principle x Rate x Time / 100

`CLS`

`INPUT ” Enter the Principal”;P`

`INPUT ” Enter the Rate”;R`

`INPUT ” Enter the Time”;T`

`LET I = P*T*R/100`

`PRINT ” The simple Interest = “;I`

`END`

**Example 10:**

FORMULA: Simple Interest = Principle x Rate x Time / 100Amount = Principle + Simple Interest

`CLS`

`INPUT ” Enter the Principal”;P`

`INPUT ” Enter the Rate”;R`

`INPUT ” Enter the Time”;T`

`LET I = P*T*R/100`

`LET A= P + I`

`PRINT ” The simple Interest = “;I`

`PRINT ” The amount=”;A`

`END`

So, these are some common **Qbasic programming examples** that are useful for students and new programmers. These posts will be updated frequently with new **Qbasic examples and exercises**, so keep visiting for more fun programming exercises.
