What is the difference between a trap, an error, a failure and program abortion?

void selectionSort (int low, int high)
{
    char *temp = malloc ((letSize + 1) * sizeof (char));
    int i = 0, j = 0;

    for (i = low; i < high - 1; i++) {
        int indexOfMin = i;
        for (j = i + 1; j < high; j++)
            if (strcmp (array1[j], array1[indexOfMin]) < 0)
                if (j != indexOfMin) {
                    indexOfMin = j;
                    strcpy (temp, array1[i]);
                    strcpy (array1[i], array1[indexOfMin]);
                    strcpy (array1[indexOfMin], temp);
                }
    }
    free (temp);
}
