file handling

how can i check the file which i intend to open exist or not?I must terminate the program if user enters non existing file.

attempt to open it. If open failes then do the error handling routine.

that's what i want to ask. Which function will i have to use.

this is c++ board, just open the file the normal way

Code:

---

ifstream in(filename);
if( !in.is_open())
{
    cout << "oops!  can't open file" << filename << endl;
    return 1;
}

---

thanks for help

Error:is_open() is not a member of ifstream

what header files did you use? (without the .h extension ??????)

Code:

---

#include <fstream>

using namespace std;
