10/12 Exercise: Complete a program with output format

Question

Please take a look at the uncompleted program in the bottom and fill in the gaps with properly output format to complete the program in order to display the following output:
把還沒完成的程式寫完
Remember: Direct output or cheated output is always forbidden.

#include <stdio.h>
int main()
{
    int x = 21, y = 0xa , z = 077;
    printf("______________ \n", x);
    printf("______________ \n", x);
    printf("______________ \n", x);
    printf("______________ \n", x);
    printf("______________ \n", y);
    printf("______________ \n", y);
    printf("______________ \n", y);
    printf("______________ \n", z);
    printf("______________ \n", z);
    printf("______________ ", z);
    return 0;
}

Required output:
