Thread: Isolate same records from one array to another.

You've put the second jdeStrncpy inside the inner if block, but it should be just after it.

The algorithm can be simplified a little bit:

Code:

    int j = 0;
    bool in_dups = false;
    for (int i = 1; i < N; ++i) {
        if (input[i] == input[i - 1]) {
            if (!in_dups) {
                in_dups = true;
                result[j++] = input[i - 1];
            }
            result[j++] = input[i];
        }
        else
            in_dups = false;
    }
