输入样例
在这里给出一组输入。例如
13 38 100
12 31 2009
2 28 2000 输出样例
在这里给出相应的输出。例如
d1 is January 1, 1900
d2 is December 31, 2009 d1 7 is January 8, 1900 d2 is December 31, 2009
d2 is January 1, 2010 Testing the prefix increment operator:
d3 is February 28, 2000
d3 is February 29, 2000
d3 is February 29, 2000 Testing the postfix increment operator:
d3 is February 29, 2000
d3 is February 29, 2000
d3 is March 1, 2000 日期的输出其中月份要用名称表示 代码实现
