    Default How do i copy this single dimension array?

    ***000***
    ***000***
    ***000***

    pixels1[] =
    (***000******000******000***)
    I need to copy the star values

    ******
    ******
    ******

    pixels2[] =
    (******************)
    Into a shorter array

    Needs to be flexible i.e

    ****0000****
    ****0000****
    ****0000****
    ****0000****
    -->
    ********
    ********
    ********
    ********

    copy of 1 dimensional[] (theoretically 2d) based on height from pixels1[] --> pixels2[]

    I don't know if this makes any sense, but any ideas would be helpful. There has to be some algorithm for it, but i can figure it out. Extra: how does one generate an algorithm for stuff like this?

    Eliminating the zeros? Count the zeros and create a new array that contains only the correct number of asterisks.

    there is no ryme or reason to the values, i just used stars and zeroes

    i need to copy and array from array1 --> array2
    array1--> /----\ height(5)
    {xxxxxyyyyyxxxxx xxxxxyyyyyxxxxx xxxxxyyyyyxxxxx xxxxxyyyyyxxxxx xxxxxyyyyyxxxxx}
    array2
    {xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx}

    i can get the height and width of both the arrays too

    There does appear to be a rhyme or reason to every example you've posted, but if that was a mistake, then start by using the Arrays methods to do what you need and go from there. You can find an explanation of the available methods on the Arrays API page.
