A sample program to implement a factory design pattern

[sunny]

Hai,

can anyone implemen this problem.I am unable to implement.i tried but i
am going out of the design pattern.

Implement the Factory Design Pattern for the following scenario:
Base class = Quad
Derived classes = Square, Rectangle
Take command line arguments for length & width. Depending upon no. of
arguments,
create and return the object of appropriate derived class. Each class
should have a
function named "desc" to print the class name. Base class should be
abstract.

Kindly find me the solution for this problem

Thanking You,

Sorry, we won't do your homework for you. And repeating the same quesiton 3
times isnt' going to help.

Show us what you've tried that didnt work. Show us code.

Speak for yourself, Jim! I'll do it for $300.us a kloc (not in my compact

$300/kloc is cheap. I'd call that disloyal competition!

I count the lines in the included system headers!! <G>

#include <iostream>
#include <ostream>
#include <string>

int main(){
std::cout<<std::string("Hello Student\n");
std::cout<<"You owe me $300.us!"<<std::endl;
return 0;
}

I need the bucks!

Why dont you show the code that you have tried. Someone may be able to
help you.

Implement the Factory Design Pattern for the following scenario:
Base class = Quad
Derived classes = Square, Rectangle
Take command line arguments for length & width. Depending upon no. of
arguments,
create and return the object of appropriate derived class. Each class
should have a
function named "desc" to print the class name. Base class should be
abstract.

Just type "Design patterns using C++" in Google and see the number of
links you get. I think the very first one is good enough.

You have work out the solution. You can only ask assistance if you run
in to problems. No one is going to do your homework.
