11-09 Exercise 1: Print a one-month calendar

Question

Write a program that prints a one-month calendar. The user specifies 2 numbers in the input:

- The number of days in the month

- The day of the week on which the month begins ( starting day of the week: 1=Sun;2=Mon;3=Tue;4=Wed;5=Thu;6=Fri;7=Sat)

寫一個程式 印出指定月份的月曆：

- 輸入一整數代表這個月有幾天

- 輸入一整數代表這個月一號星期幾 (1=星期天，2=星期一，...)

Example input:

31
3

Example output:

       1  2  3  4  5
 6  7  8  9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30 31

Hint: The most important part is a for statement that uses a variable i to count from 1 to n, where n is the number of days in a month, printing each value of i.   Inside the loop, an if statement tests whether i is the last day in a week; if so, it prints a newline.
