Aim

To write a C++ program for finding the factorial for a given number using class and object.

Procedure

STEP 1: Include the necessary header files for the program.
STEP 2: Define a class named “factorial” to encapsulate the functionality of calculating the factorial of a number.
STEP 3: Declare the member functions with in the “factorial” class.
(i)”in()” function – to get the user input.
(ii) “calculate()” function – to compute the factorial for the given input.
(iii) “out()” function – to display the result.
STEP 4: Implement the member functions.
STEP 5: In the “main()” function, create an object named “x” for the “factorial” class.
STEP 6: Invoke the member functions using the object to get the input, calculate the factorial, and display the result.
STEP 7: Terminate the program.

Source Code(Class and object)

Output

class and object

Explanation

Class and Object: In object-oriented programming (OOP), class is a blueprint or structure of an object. In this program, the “factorial” class serves as a blueprint or structure that defines the properties and functions.

Class Definition: The “factorial” class is defined with member variables (“n” and “f”) and member functions (“in()”, “calculate()”, and “out()”). These member functions define the actions or behaviors associated with objects of the “factorial” class.

Implementation of Member Functions: (i) “in()”: Gets input from the user. (ii) “calculate()”: Computes the factorial of a given number. (iii) “out()”: Displays the result.

Objects: Objects are instances of classes. In the “main()” function, an object “x” is created for the “factorial” class. This object is used to invoke the member functions such as “in()”, “calculate()”, and “out()”.

We hope this article has helped readers learn how to write a C++ program to demonstrate function overloading, default arguments, and inline functions. This C++ practical program is  included in the I year BCA TANSCHE syllabus.

How to run Java Applet

Previous
Next

Java Applet

A Java applet is a tiny application that is written in the Java programming language. They can be embedded as part of a web page. An applet is used to create dynamic platform-independent content such as animation, banners, GUIs (Graphical User Interfaces), and games for web pages.
Applets run in a sandbox environment to ensure security and are executed by the Java Virtual Machine (JVM), using:
(i) Web browser 
(ii) Appletviewer tool

To run Applet in a browser

We can embed the applet in an HTML file and execute it within a web browser. Nowadays, modern browsers do not natively support applets, but we can install a plugin to enable this functionality.
The CheerpJ Applet Runner extension is one such plugin for running Java applets on modern browsers such as Google Chrome, Microsoft Edge, Firefox, Safari, etc. It is free and easy to use. Moreover, it is completely private and secure.

(i)Create a java program(Sample.java)

1.Open any editor such as notepad or notepad++.
2. Create a folder named  “javaprogram” in D: drive(we can use any drive such as F, E, etc).
3. Type the following program and save it as “Sample.java”.

4. Open the command prompt window by typing the command “cmd” in the Windows search box.

Java Applet

5. Change the current “C” drive into “D” by typing “D:” in the prompt (because the applet program is stored in the “javaprogram” folder, which is on the “D” drive. Moreover, enter the drive name where your program folder is stored).

applet

6. Change the current working folder as  “javaprogram”  by entering the command  “cd  javaprogram”.

7. Set  the  java  path:
    (i)Navigate to the “bin” folder within the “jdk” folder. Select the path in the address bar. Right-click on the address and choose the “copy” option.

img3 2

    (ii) In the command prompt, enter the command “path” and paste the path in the prompt (Right-click in the title bar of the command prompt window, to paste the path).

8. Now compile the applet by using the following command:

To run Applet using Appletviewer

1. Function Overloading : Function overloading enables the implementation of multiple functions with the same name but with different parameters.The programmer can distinguish the functions by number of parameters, datatype of parameters and return type.
In this program, the “area” function is overloaded within the “shape” class. There are three “area” functions:
(i) The first function with an integer argument (for calculating the area of a square).
(ii) The second function with two integer arguments (for calculating the area of a rectangle).
(iii) The third function with  a double argument (for calculating the area of a circle).
This allows the program to call the appropriate “area” function based on the number and types of arguments , passed by the user.

2. Default Arguments : Default arguments provide default values for function parameters, if  there is no argument value is passed during the function call. This default argument is defined by the programmer.
In the above program, the “area” function for calculating the area of a circle has a default argument for “pi” with a value of 3.14. If the user does not provide a value for “pi” when calling this function, it will use the default value of 3.14.

3. Inline Functions :  Inline functions are functions whose code is expanded at the time of the function call, rather than being executed through a function call mechanism.
In the above program, the “area” function for calculating the area of a square is declared as an inline function using the “inline” keyword. This means that the function call is replaced with the actual code of the function during compilation, which can result in faster execution compared to a regular function call.

We hope this article has helped readers learn how to write a C++ program to demonstrate function overloading, default arguments, and inline functions. This C++ practical program is  included in the I year BCA TANSCHE syllabus.

Aim(Function Overloading)

To write a C++ program to demonstrate function overloading with default arguments and inline function by finding the area of a square, circle, and rectangle.

Procedure

Step 1: Include the necessary header files for the program.
Step 2: Define a class named “shape” to encapsulate different shape-related functionalities.
Step 3: Define various public member functions with the same name “area()” with different parameters by overloading functions with default arguments and an inline function.
Step 4: Implement the member functions to calculate the area of a square, circle, and rectangle.
Step 5: In the main() function, create an object “s” for the class “shape”.
Step 6: Get the inputs from the user and pass them through the functions , by invoking the area() member functions using the object , to find the area of square, circle, and rectangle.
Step 7: Print the results.
Step 8: Terminate the program.

How to run applet in browser

Java applet is a tiny application that is written in the java programming language. They can be embedded as a part of a web page. 

An applet is used to create dynamic platform-independent content such as animation, banners, and games for web pages.

CheerpJ plugin

Nowadays, the modern browser does not support the applet so we can install the plugin in the browser. CheerpJ Applet Runner extension is one of the plugins to run java applets on modern browsers such as Google Chrome, Microsoft Edge, Firefox, Safari, etc.

It is free and easy to use. Moreover, it is completely private and secure and runs only on the client side. The plugin is developed by Leaning Technologies.

How to Use CheerpJ plugin in a browser

1. Download and Install the CheerpJ Applet Runner extension from the Chrome web store.
2. Restart the browser and Open the web page which is embedded with an applet.
3. Click the CheerpJ icon which is in the upper right corner of the browser to enable it.
4. Now the java applet is displayed in the browser.

Step by step process to run java applet program in the browser using CheerpJ Plugin

Before  downloading and installing the plugin, create an applet from the scratch.

i. Create the java file (Sample.java)

1. Open any editor such as notepad or notepad++.
2. Create a folder “javaprogram” in D: drive(we can use any drive such as F, E, etc).
3. Type the following program and save it as “Sample.java”

4. Open the command prompt window, by typing the command “cmd” in the search box.
