萬年歷C語言設計_8537

1、精品萬年歷的設計：要求 :模仿現實生活中的掛歷，能夠顯示年歷、月歷、日歷，并具備退出功能。當前頁以系統(tǒng)當前日期的月份為準顯示當前月的每一天(顯示出日及對應的星期幾 )。當系統(tǒng)日期變到下一月時 ,系統(tǒng)自動翻頁到下一月。萬年歷的程序流程圖：主要程序流程圖 :開始Memu-slect()=3Memu-slect()=1Printf( “輸入年月日計算星期 ”)Printf( “輸入年月日計算星期 ”)Memu-slect()=2Memu-slect()=4Printf( “輸入年月日計算Printf( “輸入年月日計算星期 ”)星期 ”)結束具體對于月份和年份的程序圖如下:感謝下載載精品感謝下載載精
