help with simple code

I am just trying to make my own copy file command, and it doesnt seem to be working. Can someone help. With the attached code it only copies 7 bytes of the 56 byte picture (its a small picture). So whats up with this?

Code:

---

#include <iostream>
#include <string>
#include <fstream>
using namespace std;
int main ( int argc, int argv[] )
{
      ifstream indata;
      ofstream outdata;
      indata.open("note.gif",ios::in | ios::binary);
      outdata.open("copy.gif",ios::out | ios::binary);
   
      char send_msg[100];
      indata.get(send_msg, 100);
      outdata<<send_msg;
       

  return 0;
}

---

>indata.get(send_msg, 100);
>outdata<<send_msg;

You could use rdbuf():

Code:

---

outdata << indata.rdbuf();

Or another idea is read(), followed by write().
