Run the following program and answer the questions. #include int main() {     int a[5] = {4,16,19,12,16};     int *arr_pointer = &a[0];     *arr_pointer = a[*arr_pointer];     arr_pointer++;     printf("%d\n", *arr_pointer);     return 0; } 1. For each line of the main function (lines 5 through 8 in particular), consider how the variable a changes as the program progresses. Explain what the value of a is at each major line and why it has such value. (Hint: the gdb step command is very helpful for this problem).
