[Dev-C++] File Existence

[Farzan H. <far...@ho...>]

Hi,
I'v written a small program which simulates the DOS command "type". The =20
program receives
a file name form the command line. I used "fail()" function to check =20
existence of the received
file. I have not used "ifstream" functions a lot and I want to know =20
whether this is the
proper way to do so or not.
There is another function called "bad()". Please tell me what kind of =20
errors it can detect.
I tried it in my program and it couldn't check existence of files.

#include <iostream>
#include <fstream>
#include <cstdlib>

using namespace std;

int main(int argc,char* arg[])
{
     if(argc=3D=3D2)
     {
         ifstream File(arg[1]);
         char ch;
         if(File.fail())
             cout << "File not found!\n";
         else
             while(true)
             {
                 File.get(ch);
		if(File.eof())
		     break;
                 cout << ch;
             }
     }
     system("pause>null");
}

Thanks.
