C语言万年历设计报告

万年历的设计1幕上输出该年的年历（包括每月的天数和所对应的星期2年月，输出该月的月历。：4用于控制变换不同年、月、日的显示。即：当前若正在year表示年份的变量month表示月份的变量day表示日期的变量selecti表示月份的变量j表示一个月中的某一天的变量sum判断某天是一年中的第几天的变量a[]表示每月天数的数组变量year1系统时间年份的变量month1系统时间月份的变量day1系统时间日期的变量#include"time.h" /*#include"stdio.h"#include"math.h"#include"windows.h"#include"conio.h"#define /*#define #define #define #define #define inteachyeartotal(intyear,intmonth,intday); /*intcounterdays(intyear,intmonth,intday);intnowtime(intyear,intmonth,intday);intweek(intyear,intmonth,intday);intmaxDay(intyear,intmonth);intisleap(intyear);voidwhatweek(intyear,intmonth,intday);voiddisplay(intyear,intmonth);voiddisplay2(intyear,intmonth);voiddisplay3(intyear,intmonth,intday);voidsetDay1(intyear,intmonth,intday);voidsetDay2(intyear,intmonth,intday);voidsetDay3(intyear,intmonth,intday);voidjieri(intmonth,intday);voiddisplay1(intyear);voidgetmenu();voidmain()
