12.3.2.Reading binary file

#include <iostream.h>

#include <fstream.h>



int main () {

  char * buffer;

  long size;

  ifstream file ("example.dat", ios::in|ios::binary|ios::ate);

  size = file.tellg();

  file.seekg (0, ios::beg);

  buffer = new char [size];

  file.read (buffer, size);

  file.close();



  cout << "the complete file is in a buffer";



  delete[] buffer;

  return 0;

}

the complete file is in a buffer"
