Answer 1

//---------------------------------------------------------------------------
#include <iostream>
#include <string>
#include <fstream>

using namespace std ;

int main(void)
{
ifstream inf;
ofstream ouf;
string fsname,ftname;
char buf[1024];
cout<<"FROM:";
cin>>fsname;
cout<<"TO:";
cin>>ftname;
inf.open(fsname.c_str(),ifstream::binary);
ouf.open(ftname.c_str(),ofstream::binary);
if (!inf||!ouf) {
cerr<<"FILE ERROR"<<endl;
return -1;
}

while (!inf.eof())
{
inf.read(buf,1024);
ouf.write(buf,inf.gcount());
}
inf.close();
ouf.close();

return 0;
}
