Copying a file

[shivam]

Hi every body how are you? I'm trying to write a program in C++ that does the following: scans a folder for files, selects one of these files at random, copies the selected file to a prespecified folder, then renames this file to a another predifined name. So far I've the part that scans the folder selects a random file, I need help in copying this selected file to a another folder. Can any one please help? It will be greatly appreciated.
So far I have the following code:

#include<windows.h>
#include<stdlib.h>
#include<time.h>
#include<iostream>
using namespace std;
int main()
{
   srand(time(0));
   WIN32_FIND_DATA buf;
   HANDLE find=FindFirstFile("*.txt",&buf);
   if(find==INVALID_HANDLE_VALUE)
   {
       cout<<"No *.txt file"<<endl;
       system("pause");
       return 0;
   }
   char*file_found=buf.cFileName;
   do
   {
        if(rand()%3==0)//1 case out of 3
        {
            file_found=buf.cFileName;
            break;
        }
   }
   while(FindNextFile(find,&buf));
   FindClose(find);
   cout<<"I selected "<<file_found<<endl;
   system("pause");
   return 0;
}

I solved the problem with the following line of code:

CopyFile("source.file", "destination.file", false);

...where true or fals stands for don't/do overwrite.
