Can't copy a file. Help

Hi there. Few days ago I desided to create small program that would copy any file. But I met some realy serios problem: if file I want to copy is not a txt-file(*.wav, *.bmp, *.doc etc.) my program copies few symbols and closing file. Here's simplefied version of my program:

#include <fstream.h>

int main(int argnum, char* argu[])
{
if (argnum == 1)
{
cout << " File Copier V1.0 " << endl;
cout <<'\n'<< " Usage: filecpy.exe file1 file2 " << endl;
return 1;
};

ifstream infile (argu[1]);
ofstream fileout (argu[2],ios::app);

if( ( !infile ) || ( !fileout) )
{
cout << "\n ERROR! Enable to open/create file ! \n";
return 1;
};

char ch[60];
infile.unsetf(ios::skipws);

while (!infile.eof())
{
infile >>ch;
fileout << ch;
};

infile.close();
fileout.close();

return 0;
}

Please help me solve that problem, it realy holding be back. Thank You.

LPSTR Progname; //obviously you need to input a value to Progname
FILE *OriginalFile = fopen(Progname, "rb");
FILE *CopiedFile = fopen(Copyofprog, "wb");
int gk;
while ((gk = fgetc(OriginalFile)) != EOF);
fputc(gk, CopiedFile);
