萬年歷C語言設(shè)計(jì)

1、萬年歷的設(shè)計(jì)：要求:模仿現(xiàn)實(shí)生活中的掛歷，能夠顯示年歷、月歷、日歷，并具備退出功能。當(dāng)前頁以系統(tǒng)當(dāng)前日期的月份為準(zhǔn)顯示當(dāng)前月的每一天(顯示出日及對(duì)應(yīng)的星期幾)。當(dāng)系統(tǒng)日期變到下一月時(shí),系統(tǒng)自動(dòng)翻頁到下一月。萬年歷的程序流程圖： 主要程序流程圖:Memu-slect()=1Printf(“輸入年月日計(jì)算星期”)開始Memu-slect()=2Memu-slect()=3Memu-slect()=4Printf(“輸入年月日計(jì)算星期”)Printf(“輸入年月日計(jì)算星期”)Printf(“輸入年月日計(jì)算星期”)結(jié)束 具體對(duì)于月份和年份的程序圖如下: 上圖為計(jì)算星期方法 上圖為打印日歷程序圖 萬年歷

2、的設(shè)計(jì)的程序源代碼：#include #include #include void f()int day,month,year,sum,leap,S;printf(n請(qǐng)輸入年月日n);scanf(%d%d%d,&year,&month,&day);while(1)if(month12|month31|day2)sum+;S=(year-1+(year-1)/4-(year-1)/100+(year-1)/400+sum)%7;switch(S)case 1:printf(星期一n);break;case 2:printf(星期二n);break;case 3:printf(星期三n);brea

3、k;case 4:printf(星期四n);break;case 5:printf(星期五n);break;case 6:printf(星期六n);break;case 0:printf(星期日n);break;void g()int i,j=1,k=1,a,b,month,year;printf(n輸入年月:n);scanf(%d%d,&year,&month);while(1)if(month12|month1) printf(輸入錯(cuò)誤，重新輸入); scanf(%d%d,&year,&month);else break;b=days_month(month,year);a=firstda

4、y (month,year);printf(*n);printf( Sun Mon Tue Wed Thu Fri Sat n);if(a=7)for(i=1;i=b;i+)printf(%4d,i);if(i%7=0)printf(n);if(a!=7)while (j=4*a)printf( );j+;for(i=1;i=b;i+)printf(%4d,i);if(i=7*k-a)printf(n);k+;printf(n*n);printf(n);int leap (int year)if(year%4=0&year%100!=0|year%400=0)return 1;else ret

5、urn 0;int days_month (int month,int year)if(month=1|month=3|month=5|month=7|month=8|month=10|month=12)return 31;if(month=4|month=6|month=9|month=11)return 30;if(month=2&leap(year)=1) return 29;else return 28;int firstday(int month,int year)int W;W=(1+2*month+3*(month+1)/5+year+year/4+year/400-year/1

6、00)%7+1;return W;void h()int i,j=1,k=1,a,b,month,year,g;printf(n輸入任意年:n);scanf(%d,&year);for(g=0;g=11;g+)month=g+1;b=days_month(month,year);a=firstday (month,year);printf(%d月n,month);printf(*n);printf( Sun Mon Tue Wed Thu Fri Sat n);if(a=7)for(i=1;i=b;i+)printf(%4d,i);if(i%7=0)printf(n);j=1;k=1;if(a

7、!=7)while (j=4*a)printf( );j+;for(i=1;i=b;i+)printf(%4d,i);if(i=7*k-a)printf(n);k+;printf(n*n);printf(n);void main()for(;)switch(menu_select()case 1:printf(輸入年月日計(jì)算星期幾n);f();break;case 2:printf(打印任意日歷n);g();break;case 3:printf(打印任意年歷n);h();break;case 4:printf(謝謝使用!n);exit(0);int menu_select()char S;int cn;printf(1.輸入年月日計(jì)算星期幾n);printf(2.打印任意月歷n);printf(3.打印任意年歷n);printf(4.謝謝
