C语言程序设计万历.doc

综合性程序设计报告设计题目: 万年历 指导教师: 班 级: 学 号: _ 设 计 者: 成 绩: 设计时间: 2012年 6 月 8 日题目描述用于利用计算机实现万年历功能，包括日期对星期的转换，根据指定日期对N天后是什么日期的计算。和显示当前日期，纪念日提醒等功能。主要功能：1. 日期推算2. 日期显示3. 纪念日提醒功能模块分解及说明根据题目要求，可以用结构体实现，这个系统可以分为：年历显示、月历查询、日期查询和日期推算四个部分。其中在日期查询中包括纪念日提醒。（1） 主函数main（）主函数利用while（1）循环使得执行完每个部分之后还能回到主菜单，并利用switch函数当输入不同的值时调用不同的模块。主函数如下：void main() /*主函数*/ int year,month,day,select; while(1) dushijian(); printf("n"); getmenu(); printf(" 请输入相应数字:"); /*菜单选择 */ scanf("%d",&select); system("cls"); switch(select) case 1: /*当选择为1时显示年历*/ printf(" 年历显示：输入年（如2011）:"); scanf("%d",&year); if(year>0&&year<10000) /*显示年份从0-10000 */ display1(year); /*调用函数*/ printf(" 提示 按：上一年 按：下一年 按其他键：返回菜单nn"); setDay1( year,month, day); else system("cls"); /*清屏*/ printf(" 输入无效,重新输入!n"); break; case 2: /*当选择为2显示月历*/ printf(" 月历显示：输入年月（如2011,6）:"); scanf("%d,%d",&year,&month); if(year>0&&year<10000&&month>=1&&month<=12) display2(year,month); printf(" 提示 按：上个月 按：下个月 按其他键：返回菜单nn"); setDay2( year,month, day); else system("cls"); printf(" 输入无效,重新输入!n"); break; case 3: /*当选择为3时显示日期*/ printf(" 日期显示：输入年月日(比如2011,6,23):"); scanf("%d,%d,%d",&year,&month,&day); if(year>0&&year<10000&&month>=1&&month<=12&&day>=1&&day<=maxDay(year,month) display3(year,month,day); printf(" 提示 按PageUp：前一天 按PageDown：后一天 按其他键：返回菜单nn"); setDay3( year,month, day); else system("cls"); printf(" 输入无效,重新输入!n"); break; case 4: /*当选择4时为日期推算*/ riqituisuan(); break; case 5: exit(0); default: /*当输入其他数字时，输入无效，重新输入*/ system("cls"); printf(" 输入无效,重新输入!n"); （2） 年历显示 用来显示某一年的日历。void display1(int year) /*输出年历*/ int i; printf("n"); for(i=1;i<=12;i+) printf("%d 年 %d 月nn ",year,i); display(year,i); void display(int year ,int month) /*输出年月*/ int max,number,i,j=1; max=maxDay(year,month); number=week(year,month,1); printf(" %4s %4s %4s %4s %4s %4s %4sn","Sun","Mon","Tue","Wed", "Thu","Fri","sat"); for(i=0;i<number;i+) printf(" "); /*1号前的星期补空格*/ while(j<=max) printf("%6d",j); if (i%7=6) printf("n"); /* 每7格换一行*/ i+; j+; printf("nn");（3） 输出月历 void display2(int year,int month) /*输出月历*/ printf("n%d 年 %d 月n ",year,month); display(year,month); void display(int year ,int month) /*输出年月*/ int max,number,i,j=1; max=maxDay(year,month); number=week(year,month,1); printf(" %4s %4s %4s %4s %4s %4s %4sn","Sun","Mon","Tue","Wed", "Thu","Fri","sat"); for(i=0;i<number;i+) printf(" "); /*1号前的星期补空格*/ while(j<=max) printf("%6d",j); if (i%7=6) printf("n"); /* 每7格换一行*/ i+; j+; printf("nn");（4） 日期查询 void display3(int year,int month,int day) /*输出日历*/ whatweek( year,month,day); jieri(month,day); counterdays(year,month, day); int counterdays(int year,int month,int day) /*判断今天距特定日期的天数*/ int year1, days0,days1,month1,days, day1; time_t timep; struct tm *p; time(&timep); p=gmtime(&timep);
