fstream in_file,out_file;
out_file.open(FILENAME,ios_base::out);
char ch[] = "Hello World";
int i = 0;
while (ch[i] != '\0')
{
out_file<<ch[i++];
}
out_file.close();
in_file.open(FILENAME,ios_base::in);
i = 0;
memset(ch,0,strlen(ch));
while (!in_file.eof())
{
in_file>>ch[i];
cout<<ch[i++];
}
cout<<endl;
in_file.close();
