Namaste!!! to all c++ programmer

The  file named data.txt.  contains a different integers value.This file contains a long list of random numbers.  write a program that opens the file, reads all the numbers from the file, and calculates the following.
A) The number of numbers in the file
B) The sum of all the numbers in the file( a running total)
c) The average of all the numbers in the file.

The program should display the number of numbers found in the file, the sum of the numbers, and the average of the numbers

i m not into C++ but just wondering why u r using 201 in while loop ?
Why use constant value to read from file? what if your number changes in your file?
put a condition until u reach end of a file. use eof() function.

Namaste nepali8, good to see you are doing on your own (hope this is not copied).  As Ayus said, and you've realized too,
its not good to hard code the values. Try something like below on the above section.

                int count = 0;
  }
        cout<<"Count is "<<count<<endl;

 Namaste!!!!!!!!!!!!


Thanks Guys

1. First start by getting the applet version to run.
2. You need to use threads in this project.
3. Now look over the code and understand how the pieces work together.
4. Create a new Java project. You will be porting each of the classes from the example code to swing, so its better to code in empty class and fill in the details….feel free to rename or rethink the pieces of the program, make sure each of the next steps runs before continuing to the next step, MAKE SURE TO ADD COMMENTS TO YOUR CODE.
   1. Don’t do anything except get a blank window to open up (and close/exit correctly).
   2. Port the field class so that you can display a colored field (switch the background color to whatever you like.
   3. Port the ball class, so that you can get a bouncing ball on the screen. Don’t forget to play around with the ball color.
   4. Get the ball to bounce around the screen (for this step you can leave it as it is so that it bounces off the back wall back into the game
   5. Port the paddle so that it shows up in the game.

1. Add a score counter; so you can show the current score
2. Add a miss counter; to show how many times the paddle missed the ball
3. Add a hit counter; so that every time the ball is hit, the number is incremented….i.e. every time the ball and paddle meet, the number goes up by one.
4. Convert the ball class, it so that it works for the current window’s size….and not as it is done…i.e. if I resize the window, it will still work.
5. Make sure you are not hard coding any of your code to a specific window size
6. Change it so that if the ball misses the paddle (to the right of the paddle) it disappears and the miss counter is incremented.
7. Every 10 times you hit the ball you should get 1 point (on the score counter).

Any help with the below questions is greatly appreciated.

Switches are often prices by number of interfaces (also called ports in LAN jargon). Roughly what is the current per-interface price range for a switch consisting of only 100 Mps interfaces?

List five products on the market today that provide a Bluetooth or 802.15 interface.

Suppose that an intruder could insert DNS messages into and remove DNS messages from DNS servers. Give three scenarios showing the problems that such an intruder could cause.

Besides a power plant or an airplane cockpit, what is an analogy of a complex distributed system needs to be controlled?

 // image filters
 open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
 if (open.ShowDialog() == DialogResult.OK)
{
   // display image in picture box
   pictureBox1.Image = new Bitmap(open.FileName);
    // image file path
    textBox1.Text = open.FileName;
  }
