> how can another class interact with class employee e.g class doctor?
One class interacts with another classes by means of object instances. You can always pass on object instance of one class to the member function of another class. In fact we do this all the time without even realizing it:

// here str is a object instance of class string
string SomeClass::modifyString (string str)
{
   // process
   return str;
}

> How is it possible to improve an object of a class?

What do you exactly mean by this ? Maybe the generalization and specialization relationship. Consider for example an Account class.

An Account class is the generalization of Savings, Fixed and Current account types (a fixed account is a type of Account). On the other hand a FixedAccount class is a specialization of the generic class Accounts.

Thus the Savings class will have data members which the Fixed account might not have but they all will definately contain the members of their super class Account depending on the access specifiers specified and so on. (public, private, protected)

XXX for me... :D

BTW, INTP here.

But the question here is, why not just erase it ? Is it a requirement ? BTW, you can get all the reference to vector methods here.

Read the links posted by me in the second post.

An eg.

string inStr;
string searchFor = "hello";
ostream in ("test.txt");

while (getline (in, inStr))
{
    if (inStr == searchStr)
    {
        //process
    }
}

Check if the distance between the center of your square and the random point is less than equal to the radius. If so then the dart has hit the spot otherwise its a miss. This validation should be easy to perform using the distance formula.

Try using the erase method of vectors instead of popping them. Read this.

Hey there my friend, welcome to Daniweb :D

Just replace the ++current in my previous code with current += 2 and make the data type of the variable value as double and you should be good to go.

Maybe something like this:

double factorial (double value)
{
    double result = 1.0;
    while (fabs (value) > 0)
    {
        result *= value--;
    }
    return result;
}

int main ()
{
    double summand = 0.0, sum = 0.0;
    int value = 0, current = 0;
    bool flag = true;

    cout << "Enter the power of e whose answer you want: " ;
    cin >> value;
    getchar ();

    do
    {
        summand = pow ((double)value, (double)current) / factorial (current);
        if (flag)
            sum += summand;
        else
            sum -= summand;

        flag = !flag;
        ++current;
    }
    while (summand > 0.00001);
    cout << "\nAnswer is : " << sum;

    getchar ();
    return 0;
}

I still see a while loop in your code. On top of that the while loop uses the value of i which is 5 when the while block is entered (since you never reset it after the for loop).

Stop checking for the occurance of zero in the loop. Just make it like the loop you used for accepting user input.

You are welcome. :D

Thread solved.

The alteration is happening alright. Your logic is wrong. Look at it once again. Are you sure you are doing what the equation demands ?

Some good links for File processing in C++ are here, here and here.

Maybe you need to look a bit harder at the code I posted. It takes care of changing the flag variable. Look out for the part posted in bold...

All famous compilers come with a host of features and some kind of IDE. If minimalism is what you want, you can go for command line compilers but they just end up sucking your blood if you haven't used them before.

Good, then go for WinAPI.

A good starting place would be this and the MSDN if you get stuck.

Keep a flag variable which will decide whether the operation should be addition or subtraction.

{
   double summand = 1;
   int n = 1;
   double sum = 1;
   bool flag = true;
   do
   {
      summand = summand * x / n;

[B]      if (flag)
           sum += summand;
      else
           sum -= summand;
      flag = !flag;[/B]

      n--;
   }
   while (summand > 0.00001);

   return sum;
}

Post what you attempted so far or start reading the stickies at the top of C++ forum to aid you in programming.

Some points:

1. Use code tags to post your indented code so that it is more readable.

2. The loop you use for input can easily cause buffer overflows if zero is not entered by the user. If you know the array size in advance, replace all the cumbersome while loops with the for loops and repost your updated code.

3. You did a mistake in placing the logic for finding out the highest in the else block. Place it in a seperate if block.

4. Initializing your variables will save you a lot of head banging in the future. Always initialize your variables before using them in such situations.

Some points:

• Post your code in code tags.

• Don't use gets for accepting input from the user. Read this.

• Remove the semicolon after the if statement in your function. Its ruining your logic.

• m = (char) str1; The above statement doesn't do what you expect it to do. It converts a address to character, something which you don't want here.

I challenge you to supply a satsifactory answer!

My friend, I hope you do realize this is no battle ground where we can challenge our friends to duel... ;)

I am working on a program that uses the graphics.h library functions
and the 0x33 mouse interrupt. When I click at a particular place on the
screen, the graphics nearby the mouse are saved and displayed on the
new screen (that appears due to the mouse click) when the mouse
position is changed. The same happens when I drag the mouse from one point to another.

You need to post the screenshots or atleast the code so that we can get an idea of how things currently stand.

Its first time for you, not for us.

And btw, you already must have got the warning for not adding code tags. Remember to use them in the future.

Bumping your posts would do you no good. It would only result in a longer delay and is not encouraged. Patience wins the best help.

I dont get it , what do you mean by "diffrent variables to keep track of the indexes" ?can you give me an example ?
thanks.

You just have to make sure that the element you have to remove doesn't make it into the new array.

This depends on the way you want the removal to happen. For eg. you can do position based removal or value based removal.

And btw, are you sure you have to create a new array? Normally these kinds of exercises require you to make changes in the original array itself using realloc .
