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：具體對于月份和年份的程序圖如下z上圖為打印日歷程序圖上圖為計(jì)算星期方法萬年歷的設(shè)計(jì)的程序源代碼：#include<stdio.h>#include<stdlib.h>#include<ctype.h>voidf()(intday,month,year,sum,leap,S;printf("n請輸入年月日n&qu
