This problem is geting disgusting.

I've been having a reccuring problem with my code for around a month now where the code compiles fine, however, the file is not created. While at my friends place, (using dev bloodshed C++ v.4 if it matters) He points out to me that I put "fstream" rather than "ofstream". Success! My code finaly does what it should. However, when I get home (dev bloodshed C++ v.5) and add the aforementioned "ofstream" it does NOT create the file. Here's my code.

PS: The function "readInCustomer" is my begining to experiment with reading in the file, I'm not 100% on how this works, however, if anybody has any better ideas I'm open to them.

If you wish to overwrite the file, make sure line 50 reads


CustomerFile.open("C:\\DoNotDelete.txt", ios_base::trunc );

Between lines 50 and 51 you should check that the file was actually opened and writable:


if (!CustomerFile) fooey();

(It may not be if you don't have high-enough permissions.)

I hope all those system("PAUSE")s and system("CLS")s are temporary...

Hope this helps.

Thanks a bunch, I'll try it out.

And this isn't a professional program, just a little thing of my own, so I'm not to worried about systempause and systemcls, but I'll do my best to remove them.

I figured that was the case. Good luck!
