Im missing something (infile)

here the code first off:

Code:

---

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main(int argc, char* argv[])
{
        string FileLocation;
        string Extension = ".cpp";
        bool Quit = false;
        ofstream        outfile;
        ifstream        infile;

        cout << "Enter path to file (no ext please): ";
        getline(cin,FileLocation);
        FileLocation += Extension;

        infile.open("FileLocation");

        return 0;
}

---

It never loads the file even if its entered correctly. I did a test cout so i know its the infile line. My theory is that the FileLocation is taken as a literal not a variable because of the quotes. Problem is i cant built it without quotes, so how can i accomplish this? I know its a lame question but never tried it before.

That's exactly right. Why are you using quotes? That makes it a string literal, not a variable name.

Quzah.

Well i didnt use them at first but it produced this error, how do i get around it? Different function for infile?

Open accepts a const char*

Try this

Code:

---

infile.open(FileLocation.c_str());

---

no errors but it apparently isnt opening cuz this while i added under it doesnt execute:

Code:

---

while(!infile.fail())
        {
                cout << "cool" << endl;
        }

---

fixed, thnx for all the help.

ok new question, i searched but couldnt find what i wanted.

After i open the file i create a directory called "CPP BACKUP" on the c:\ drive. How can i make a copy of the file i opened, an exact copy, and move it to the backup folder?

i know i could read in all the data from the file then make a new one, but surely i can copy and place the copy in my folder?

I tried searching i cant find my answer anywhere :confused:

One way if you are running Windows:

CopyFile("oldfilename","\\CPP BACKUP\\newfilename",TRUE);

Yea that will do it, thank you much. Last question, how can i check to see if a folder alrdy exists? Like

if (! this directory exists)
{
create it here
}

Nothing shows up in the folder snoop.

If your compiler has the stat() function, you could use this to see if a file or directory exists.

Or in windows, you could use:
GetFileAttributes("dir");

Or:
FindFirstFile("dir",...);

i'll give that try
