Hi,

I have taken an assignment on C++ which at first glance looked very simple. Just multiply 2 numbers! The teacher smiled at me. But now I realized why!

The numbers I have to handle are more than 30 digits. So I won’t be able to just use * !

Looks like I am in big trouble. How do I do such big number multiplication in C++.

Hi there,

I am experiencing a very frustrating issue concerning my Yahoo Messenger program. I have been using this application for many years and I have not encountered an irritating issue as this. The issue I am facing now is that I cannot sign-in to my Yahoo account using the Yahoo Messenger app. Whenever I tried to log into it, the trouble shooting dialogue appears for a few seconds and then disappears.

To handle this issue: First, I tried a totally un-installation and re-installation of Yahoo Messenger. Yet, still I cannot log in. Second, I installed the new version of it, but...

Hi there,

I am learning coding in C++. I would like to start, by making a full functional calculator.  All of them are pretty done but I want some more options which are present in a scientific calculator, like binary calculation.  I don't see any function for this. So I guess I have to make one.

I have been trying to add the binary to decimal conversion. I know that the basic process is:

But how do I take the digits 1 at a time.  Should I take the binary number as a string...

Hello Everyone,

I have created a connected graph, where each node represents some fact. The centre is the point of start. You may think of it as a mind map. I want to search the map in a Depth First Manner. I understand the concept but don't know how to apply it. Here is a pseudocode

dfs(vertex v)
    {  
  visit(v);
    for each neighbour w of v
        if w is unvisited
        {
        dfs(w);
        add edge vw to tree T
        }

   }


I am really confused on...

Hi,

I am doing some analytical program in C++ involving a lot of prime numbers. I don't think checking a number every time, whether it is prime or not would be a good idea.

So I just thought that if I could pre generate all the prime numbers in a list.

But it is taking too much. Time.

vector<int> prmn;
For (int i=2; I<100000; ++i)
If (isprime (I)) {
prmn.push_back(i);
}

Almost 4-5 second. I hate to find it upto 1000,000.

Is there any better way?
