So far i can only make it to operate 1 output at a time but not both. Does any1 have a suggestion? (fyi: the...

    [SOLVED] How do i count the duplicate number for the last one... (codeblock)

    oh what i mean by "bool" is the command bool matching = false; for (int j=0; (j<i) && (matching == false); j++) if (x[i] == x[j]) matching = true; if (!matching) since i only find this method on the internet so i just modify it just curious if there is more simple method thats all :thinker:
