    Given the array variable data of type array<N,int>, consider the code:
    for (int i=0; i<N-1; i++) {
    if (data > data[i+1]) {
    int t = data;
    data = data[i+1];
    data[i+1] = t;
    }
    }
    Explain how this code changes the value of data.
    If     N = 5 and data has the initial value
    < 6; 3; 4; 7; 1 >
    what will be the value of data after executing this code?

    Just want to see am I on right track, for i=0 data changes to
    <3;6;4;7;1>
    for i = 1
    <3;4;6;7;1>
    i=2
    no change
    i=3
    <3;4;6;1;7>

    Hey is the above the anwser? and if not where am II going wrong?

    Cheers...!

    What you said looks fine to me, after a quick glance.

    If in doubt, why not just step through it in a debugger, or compile in some print statements to verify your reasoning?
