hmm, question!

I wrote this K-Journal program out of complete boredom, when I compile it under C++ Specs it works, when I compile under C it does not work, can someone explain why and if possible explain what I should do so I can compile it under C

This works. It was your file pointer. I think...

File *fp; first

THEN..

fp = fopen....

That could be one reason.

Explanation:
File pointer assignments always come first. Later on, you use the actual pointer to do file work.

Beinning of code:
FILE * MyFileToUse;

Later on in code:
MyFileToUse = fopen("c:\\foo.txt", "attributes");
fprintf(MyFileToUse, "blahblahblah\n");
fclose(MyFileToUse);

- edit -
In c++ you can assign them anywhere. In C you have to put them at the beginning of your function. I learned that the hard way.

thanks!
