In the same directory as the .exe might be a choice. As would the "root" directory of your project. IDE's, when running a program, can often be told where to assume the current directory is.

Your prototype and implementation do not match.

Is the process doing the waiting for A to end, the one that started A in the first place? Just use the wait command, if it is.

The best place is project->settings->preprocessor and set the flag there.

Well if you compile with debug, say gcc -g prog.c Then try gdb a.out Followed by 'run' at the debugger prompt, it will catch the fault and point you at the offending line of code.

When (as you have, after Dave's formatting), you see 6 closing braces in a row, and the last one is over 300 lines from it's buddy, then it's time to REFACTOR. Add some functions man, there is no reasonable way to test that code in an incremental fashion.

> I mean ultimately, I would expect that 10.10 should be greater than 10.5 when we compare both double values. Huh? So if I wrote the same values as 10.10 and 10.50 would that change anything for you? Because it doesn't change anything for the compiler, or the numbers.

So does it work? What do you see in LOG_File? Have you looked at the -d option of the FTP command? Are there any diagnostics in your firewall (about trying to use a particular port)?

You just described classes and operator overloading. class myLongInt; Then later myLongInt a, b, c; With suitable initialisation, and an appropriate method or two, you can do c = a + b;

> On the other hand, I then instantiate another object using the class's copy constructor and it creates this error, any ideas? You don't initialise mFirst in the current object before trying to append.
