程序可以实现如下三种功能：求某个日期对应的星期求某年某月有的天数输出某年的日历.例如,打印2006年日历如下:-------------------------------------------------------------------------- 2006 年-------------------------------------------------------------------------- 一月二月周日周一周二周三周四周五周六周日周一周二周三周四周五周六 1 3 5 7 9 11 13 1 3 5 7 14 15 16 17 18 19 20 8 9 10 11 12 13 14 21 22 23 24 25 26 27 15 16 17 18 19 20 21 28 29 30 31 22 23 24 25 26 27 28 三月四月周日周一周二周三周四周五周六周日周一周二周三周四周五周六 1 3 5 7 1 8 9 10 11 12 13 14 2 3 4 5 6 7 8 15 16 17 18 19 20 21 9 10 11 12 13 14 15 22 23 24 25 26 27 28 16 17 18 19 20 21 22 29 30 31 23 24 25 26 27 28 29 30 五月六月周日周一周二周三周四周五周六周日周一周二周三周四周五周六 1 3 5 7 9 11 1 3 5 12 13 14 15 16 17 18 6 7 8 9 10 11 12 19 20 21 22 23 24 25 13 14 15 16 17 18 19 26 27 28 29 30 31 20 21 22 23 24 25 26 27 28 29 30 七月八月周日周一周二周三周四周五周六周日周一周二周三周四周五周六 1 1 3 5 7 9 2 3 4 5 6 7 8 10 11 12 13 14 15 16 9 10 11 12 13 14 15 17 18 19 20 21 22 23 16 17 18 19 20 21 22 24 25 26 27 28 29 30 23 24 25 26 27 28 29 31 30 31 九月十月周日周一周二周三周四周五周六周日周一周二周三周四周五周六 1 3 1 3 5 7 9 11 13 4 5 6 7 8 9 10 14 15 16 17 18 19 20 11 12 13 14 15 16 17 21 22 23 24 25 26 27 18 19 20 21 22 23 24 28 29 30 31 25 26 27 28 29 30 十一月十二月周日周一周二周三周四周五周六周日周一周二周三周四周五周六 1 3 5 7 1 3 8 9 10 11 12 13 14 4 5 6 7 8 9 10 15 16 17 18 19 20 21 11 12 13 14 15 16 17 22 23 24 25 26 27 28 18 19 20 21 22 23 24 29 30 25 26 27 28 29 30 31 原代码如下: 一,非打印版(:即只能输出到屏幕,不可输出到文件) /*万年历全集：程序可以实现如下三种功能：求某个日期对应的星期求某年某月有的天数输出某年的日历*//*2006-1-2 梁见斌*/#include<stdio.h>#include<stdlib.h> struct mon{ int maxdata;
