Hi everybody,

I have lots of trouble when I try to use stable_sort algorithm so Ican
readjust hte TPoitn values
within TPoint arrea in the following manner

TPoint OldArray[4], NewArray[4];

OldArray[0].x = 200; OldArray[0].y = 400;
OldArray[1].x = 300; OldArray[1].y = 300;
OldArray[2].x = 100; OldArray[2].y = 500;
OldArray[3].x = 150; OldArray[3].y = 200;

The value within NewArray would be something like this:

NewArray[0].x = 150; NewArray[0].y = 200;
NewArray[1].x = 300; NewArray[1].y = 300;
NewArray[2].x = 200; NewArray[2].y = 400;
NewArray[3].x = 100; NewArray[3].y = 500;

However, the BCB6 compiler keeps complaining as follows:

[C++ Error] _function_base.h
"E2093 Operator 'operator <' not implemented in type 'TPoint' for
arguments of the same type"

How can I dealwith this kind of problem? Any alternative so I can dela
with stable_sort problem wihotu headache .....
