Object Orientation Enlarged by an Example!


This program illustrates how to implement the arithmetic operation in an object oriented way.

Here we have a class with 2 variables. For each operation an object of this class is created to do the operation instead of declaring such much variables. Therefore, this method is, for a large scale implementation, is quite efficient.
so have a try on it.



Program:


//simple operations in object oriented method
#include<conio.h>
#include<iostream.h>

class dom
{
int a,b;
public:
void get()
{
cout<<"oops..!\nnumbers:";
cin>>a>>b;
cout<<"passed";
}
void add()
{
cout<<endl<<"a+b="<<a+b;
}
void diff()
{
cout<<endl<<"a-b="<<a-b;
}
void mult()
{
cout<<endl<<"a*b="<<a*b;
}
void div()
{
cout<<endl<<"a/b="<<a/b;
}

};

void main()
{
clrscr();
dom add, mult,diff,div;

cout<<"\n+";
add.get();

cout<<"\n-";
diff.get();

cout<<"\n*";
mult.get();

cout<<"\n/";
div.get();

cout<<"\n\nprocessing...";

add.add();
diff.diff();
mult.mult();
div.div();
cout<<"\n\nover";
getch();

}

Have u tried this?

How to pass variables to res.render() in Node.js

I was trying to figure out how to render a view inside a view, as I was stuck with this issue.

Horrible Effects of Misplaced Extensions ;)
I was using Node.js platform with ejs template engine.

My index.ejs file has an included header.ejs file.
Everything works well except that I can't pass values to the variable status in header.ejs.

Here is my abstract code...

index.ejs

header.ejs

app.js

The most funniest solution ever!
The solution is as easy as this.
Just remove .ejs extension from the include command.
I spent at least an entire night to figure it out.

Talky Messenger Documentation & Setup

(Github)
Just created a chat app that runs in Node and Socket. By the Grace of God, this attempt was worthy.

Talky is a messenger app built with Node, Express, Socket, Angular & Bootstrap.
It's like a server-client structure. (But obviously not like the one we done at OS lab using shared memory). It has a broadcasting structure. Talky does not keep a log on chat. i.e., It doesn't have a memory or database. When we close the browser window, chat history is lost. There I also added a basic console, protected by a password, to send real-time notifications to active clients.

The name 'Talky' was suggested by a friend of mine. (hey, thank you for that. The fact is that I am not really good at naming...😝)

What if sometimes your college blocks WhatsApp? Try Talky.

(There is also a website on internet in the name of 'Talky' which has no connection with this one.)
