What is wrong with my code?

When I compile and run the code below, I get an error message like this :

> File 'c:\mysql\\share\charsets\?.conf' not found (Errcode: 2)
> Character set '#33' is not a compiled character set and is not specified
> in the

> Error occured while connecting.
> Error code   : 1251

> Press any key to continue . . .

Notice the double backslashes in the path strings "c:\mysql\\share\charse...".
Is that normal?
I looked for sample codes by using Google, and all the example codes I found
are similar to mine.
Maybe one small difference is the use of mysql_init(); function. In some
examples it is used in this way :
mysql = mysql_init(NULL);
Bu I don't think it is what causing the problem.

What should I do to get rid of this problem?
Am I doing something wrong?
