Hi Mirek,

Thanks, I used most of your ideas.

Dear all,

Because this post seems to catch some interest please find attached my solution (XP's zip). The functions

String 		cleanup(String s);
Vector<String>	getLines(String s);
String 		load(char* filename);
bool 		save(const char *filename, const String& data);
String 		ToString(const Vector<String>& vs);
Vector<String>	transpose(const Vector<String>& vs);

help to convert input.txt

 A,	B  , 	 C		,D	
1,10  ,   100,	5
		2,20 , 200,55

into output.txt

A,1,2
B,10,20
C,100,200
D,5,55

Any suggestion, feedback or comments are welcome. This code so far does just the required minimum. I.e. it will fail when the number of elements vary. I wonder how to take care of such issues, e.g. through throwing exceptions (try, catch) or else?

What would you do?

Kind regards,
Micha
