1) uni() function for making a unique array
2) the main function read a txt file which is include

rectangle 0 0 1 1 orange
rectangle 0 1 1 1 green
rectangle 0 2 1 1 white
rectangle 0 3 1 1 orange
rectangle 0 4 1 1 white
rectangle 0 5 1 1 black
rectangle 0 6 1 1 blue
rectangle 0 7 1 1 red
rectangle 0 8 1 1 blue
rectangle 0 9 1 1 white
rectangle 0 10 1 1 green
rectangle 0 11 1 1 green

something like that (1000 or more line ).
then i want to filter only colour name without duplicating. But my program doesn't work .it produce all colour (with duplicate colour name).. I tested uni() function it works properly. Why my program doesn't work properly (i want to print out only colour name without duplicated )..

you've had 5 separate threads in the past month on this same program.

and theres no functional difference between this program and the one you posted four days ago with Narue.

i'm just sayin'

You should also consider marking your threads as solved when you consider them solved. IMHO its kind of rude to repeatedly get help and not bother saying thank you by marking as solved.
