Paint Brush In C (Project)
--------------------------------------------------------------------------------
Description : Paint Brush is intresting paint program which has
symmetry function which give some good designs. This program is
same as MSPaint with some more/less features. Save the Program
in two files paint.c and mouse.c in same directory and compile
each file and run paint.c.
