Question

一道C++日历题，哪位大哥帮我做一下啊～急！！！！ 有加分

Write a program that prints a calendar for a year. Prompt the user for which day of the week
January 1 is on and whether the year is a leap year. The day that January 1 is on is coded as
follows:
Sun 1
Mon 2
Tue 3
Wed 4
Thu 5
Fri 6
Sat 7

-----------------

Sample Output:

Enter the day for Jan 1:
[1 - Su, 2 - Mo, 3 - Tu, 4 - We, 5 - Th, 6 - Fr, 7 - Sa] : 5
Is this a leap year: [0 - No, 1 - Yes] : 1

January

Su Mo Tu We Th Fr Sa
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
（以此类推）
