You can specify a full path when you create a file, eg in Linux

Code:

myfile.open("/home/xsky/newfile.txt");

(see the MSDN for full path naming in a Windows environment)

Or you can chdir to change the current working directory so that files that are created will be in the new working directory, rather than the one where the executable starts. (SetCurrentDirectory in Windows)

I'm not quite sure if you just mean to run another executable from within a C++ program? You can use the system call if that is what you mean. (CreateProcess in Windows)
