How to calculate the total number of created objects for a particular class in C#/C++?

How do you calculate the total number of created objects for a particular class in C#/C++?

This could be one of the question to in any technical interview. So what is the solution??

suppose think that you have a class abc.

class abc
  int x=10;

now if you create the object of the class:
abc a1=new abc();
abc a2=new abc();

now the total number of objects are 2. But how do you calculate it programatically??
Below is the solution:

class mainClass
        static void Main(string[] args)
            abc a1 = new abc();
            abc a2 = new abc();
            abc a3 = new abc();
            abc a4 = new abc();
            abc a5 = new abc();
            abc a6 = new abc();

    class abc
        public static int count = 0;
        public abc()

Hope it helped you :)

Remove Pendrive Shortcut Virus without Antivirus

Have messed up with the problem where your pendrive has only shortcuts of all the folders or 

you can see only one shortcut of your pendrive and there is no data when you open your pendrive , even though it shows the memory occupied,  when you see its properties ???

Then here is the solution for this virus without having an Antivirus.. :)
Step 1:
 Download Autorun Exterminator

Extract ithe zipped file, double click on "AutorunExterminator" then Plug your pendrive now.
This will remove the autorun.inf files from drives.

Click on "Start">Run >type cmd and click on OK.

Here I assume your pen drive letter as F: 

Enter this command.

attrib -h -r -s /s /d f:\*.*

You can copy the above command.  Right-click in the Command Prompt and paste it. 

Note : Don't forget to replace the letter f with your pen drive letter. 

Now press "Enter". That’s it!!!!
Now check for your files and folder in Pen Drive.

If there are any Shortcut folders, just delete them. you wont loose any data.
