Start with where you want to start:
int main(void)
{
	FindCPP( "C:\\");
	return 0;
}
Then, find the files:
void FindCPP( char*path)
{	static depth = 0;//for illustration use if you want
	int	done;
	char	mypath[256];
	struct  ffblk  fb;
	fnmerge( mypath,NULL,path,"*.cpp",NULL);
	done = findfirst( mypath, &fb, 0 );
	// first, find all the files in this folder
	while (!done) 
	{
	     // you could use depth here to indent the display
	      printf("  %s\n", fb.ff_name);

	      done = findnext(&fb);
	}
	findclose( &fb);
	fnmerge( mypath,NULL,path,"*.*",NULL);
	done = findfirst( mypath, &fb, 0 );
	// then recurse through all the subfolders
	while (!done) 
	{
	    if(  (fb.ff_attrib&FA_DIREC) ==FA_DIREC )
	    {  if( fb.ff_name[0] != '.' ) // ignore '.' and '..' dirs
	        {	fnmerge( mypath, NULL,path,fb.ff_name,"\\");
		++depth;
		FindCPP( mypath );
		--depth;
	    }  }
	    done = findnext(&fb);
	}
	findclose( &fb);
}
Note that this is just written, and untested.
There may be typeos, and the fnmerge functions might need added
slashes between the old path and the new ff_name, in which case, use
strcpy/strcat instead.  A good defense woulde be to check the passed
path for an ending '\\' at the very beginning of the function.
