c语言课程设计报告--万年历C 语言课程设计报告C语言课程设计报告实验课程：c语言课程设计年级：软件2班实验成绩：课程设计名称万年历姓名：**任课教师：杨** 学号：**** 实验日期：2014.6.11一、目的利用所学的知识解决生活中的实际问题。

本课题涉及的知识内容：时间函数，tm结构，for，do..while循环嵌套，if语句，指针，函数回调，结构体函数，文件创建与保存，自定义函数等语言内容。

二、内容与设计思想1．设计内容①显示系统当前时间②查询用户输入的时间③在用户输入的时间上，进行下一步的查询④对用户所需日期添加备忘，可供查看和添加2．主要代码结构main()函数调用了菜单函数，通过菜单函数来调用各个不同功能的函数。

3．主要代码段分析。

先显示系统时间，再通过列一个菜单来调用各个功能的函数；Themonth函数实现了对用户输入日期当月的处理，例如：日期的显示，日期与周几的对应等等。

Nextstep函数则是对输入日期的后续操作. Writetext、Readtext,、Changetext函数是对备忘录方面的操作，主要功能分别是写备忘，查看备忘，修改备忘。

三、使用环境本次上机实践所使用的平台和相关软件。

平台：Windows 2000相关软件：VC++四、调试过程1．测试结果分析经检验，运行结果正确五、总结1．设计中遇到的问题及解决过程调试过程中往往一个月的第一天与相对应的星期几对上比较棘手，通过查阅资料，找到了相应的函数；解决了问题备忘方面设计有关文件的读取方面的知识，在此之前，对文件的读取，修改比较，生疏模糊。

通过看书和上网寻找有关文件读取方面的例子，对文件有了初步的认识和应用。

期望备忘录功能中有修改功能，后期实在解决不了，换成了较为简单的添加功能。

2．设计体会和收获。

学会了如何通过现有资源解决问题；对c语言的有了更深的了解六、附录1．源代码#include "stdio.h"#include "time.h"#include "malloc.h"#include "stdlib.h"#include "string.h"typedef struct text{int num;char date[100];}Text[30],*pText;//函数声明void in_menu(void);void menu(void);void themonth(int,int);void nextstep(int,int);void Writetext(pText);void Readtext(void);void addtext(pText);void exit_calendar(void);int thelast(FILE*);//总菜单void allmenu(void){in_menu();//输出菜单menu();//选择菜单}//输出菜单void in_menu(void){printf(" △○日历查询及备忘系统○△\n");printf("\n");printf(" ===================1、日历==============================\n\n");printf(" ===================2、编辑备忘=========================\n\n");printf(" ===================3、查看备忘===========================\n\n");printf(" ===================4、添加备忘===========================\n\n");printf("====================5、退出==============================\n\n");printf("******************************************************* *********\n\n");printf("请选择菜单号码：");}//菜单选择void menu(void){struct text t;int i;scanf("%d",&i);switch(i){case 1:{//当前查询的月份int year;int month;printf("请输入要查询的年份及月份：\n"); scanf("%d %d",&year,&month); themonth(year,month);printf("按回车键返回主菜单!\n"); getchar();getchar();system("cls");allmenu();break;}case 2:{Writetext(&t);//写备忘printf("按回车键返回主菜单!\n"); getchar();getchar();system("cls");allmenu();break;}case 3:{Readtext();//查看备忘内容printf("按回车键返回主菜单!\n"); getchar();getchar();system("cls");allmenu();break;}case 4:{addtext(&t);//修改备忘printf("按回车键返回主菜单!\n"); getchar();getchar();system("cls");allmenu();break;}case 5:{exit_calendar();}default: break;}void nextmenu(int year,int month){int j;printf("===================1、结束本次查询,回菜=====================\n");printf(" ===================2、继续查询============================\n");scanf("%d",&j);if(j == 1){allmenu();}else{nextstep(year, month);}}/************************查询的当月*/void themonth(int year,int month){//定义变量struct tm t,*date;//tm结构指针time_t t_day;//声明time_t类型的变量t_dayint i,j;int day;if(month == 2 )//月份天数的判断if(year%4 == 0&&year%100 == 0||year%400 == 0)day = 28;elseday = 29;}else if(month == 4 || month == 6 || month == 9 || month == 11)//小月{day=30;}elseday=31;printf("查询日期当月天数是：%d\n日历\n",day); //输出当前天数printf("一\t二\t三\t四\t五\t六\t日\t\n"); //日历的第一行，显示一二三四五六日//功能：使当月中的每一天与对应的周几对齐for(i = 1;i <= day;i++){t.tm_year=year-1900;//从1900开始t.tm_mon=month-1;//月份【取值[0-11]】t.tm_mday=i;//一个月的日期[1-31]t.tm_hour=0;//时-取值区间t.tm_min=0;//分-取值区间t.tm_sec=0;//秒-取值区间t.tm_isdst=0;//夏令时标识符，实行夏令的时候为正否则为0t_day=mktime(&t);//date=gmtime(&t_day);if(i==1)for(j=0;jtm_wday;j++)printf("\t");}if(date->tm_wday == 6){printf("%d\n",i);}elseprintf("%d\t",i);}printf("\n\n");nextmenu(year,month);}bool sfnext(int * k)//判断是否继续{if((*k) == 1)return true;elsereturn false;}//是否进行后续操作void nextstep(int year,int month) {int m,k;do{printf("月历上翻请按-1，下翻请按1\n"); scanf("%d", &m);system("cls");if(m == 1){month += 1;printf("现在查询时间为%d年%d月的日历：\n",year,month); if(month/12 != 0){year = year + month/12;month = month % 12;}themonth(year,month);printf("是否继续查询，是：请按1\n");printf("否：请按0\n");scanf("%d",&k);}else if(m == -1){month -= 1;printf("现在查询时间为%d年%d月的日历：\n",year,month); if(month == 0){month = 12;year--;}if(month <= 0){month += 12;year--;}themonth(year,month);printf("是否继续查询，是：请按1\n");printf("否：请按0\n");scanf("%d",&k);}else{printf("error");}}while(sfnext(&k));}//读文件void Writetext(pText t){int len;char n;//读取文件FILE *fp;if((fp = fopen("C:\\text.txt","a+"))==NULL)//a+:以读写方式打开一个文件，允许读{printf("Cannot open the file ,press any key to exit");getchar();exit(0); //退出程序}printf("是否确定对某年某月某日进行备忘：y或n\n");getchar();scanf("%c",&n);if(n == 'y'||n == 'Y'){printf("请输入要添加备忘的数量：\n");scanf("%d",&len);printf("按格式输入(如：1 2014 6 17 c语言作业)\n");//输入需要备忘的年月日for(int i = 0;i < len; i++){printf("Num%d:",i+1);scanf("%d %s",&t[i].num ,&t[i].date);fprintf(fp,"%d %s\n",t[i].num ,t[i].date);//格式化读写}fclose(fp);}else{exit(-1);}}//判断文件是否读完int thelast(FILE*fp){if(fgetc(fp) == EOF)return 1;else{fseek(fp,-1L,SEEK_CUR);return 0;}}//查看备忘内容void Readtext(void){static char c[200];//文件输入FILE*fp;if((fp = fopen("c:\\text.txt","r")) == NULL){printf("文件不存在，按任意键退出.");exit(0);}else{printf("序号\n备忘内容\n");while(!thelast(fp)){fscanf(fp,"%s",c);//读取文件中的信息printf("%s\n",c);}printf("\n");}}void addtext(pText t){FILE *fp;int n,m;if((fp = fopen("C:\\text.txt","a+"))==NULL)//a+:以读写方式打开一个文件，允许读{printf("Cannot open the file ,press any key to exit");getchar();exit(0); //退出程序}printf("请输入要继续添加备忘的数量：\n");scanf("%d",&n);printf("已备忘数量:");scanf("%d",&m);printf("按格式输入(如：1 2014 6 17 c语言作业)\n");//输入需要备忘的年月日for(int i = 0;i < n; i++){printf("Addnum%d:",i+m+1);scanf("%d %s",&t[i+m].num ,&t[i+m].date);fprintf(fp,"%d %s\n",t[i+m].num ,t[i+m].date);//格式化读写}fclose(fp);}void exit_calendar(void)//退出系统{exit(1);}//主函数void main(){time_t now;//声明time_t类型变量time(&now);//获取时间printf("\n\t\t现在是:%s\n",ctime(&now));//系统时间allmenu();// nextstep(year, month,&t);//对当前月份的后续操作}。

输入1，通过输入当前日期可显示当前月的日历；输入2，通过输入具体日期（中间以空格分开）可显示该日具体信息；输入3，则退出查询系统。

第3章概要设计1．菜单选择界面可通过下面所示函数时现；主要思路：通过while语句与swich…case以及if条件语句实现菜单的循环功能和不同选项的功能实现。

闰年与平年的判断：代码如下：void main(){int year,month,day,a,b;while(1){printf("\n\n\n\n");printf("**********************************************************\n\n");printf(" * * \n");printf(" Welcome to enter calendar system \n");printf(" * * \n\n");printf("**********************************************************\n\n\n");printf(" 1 The month of current date 2 Date 3 Exit\n");printf(" please import your choose<1~3>,press Enter to define: ");scanf("%d",&b);switch(b){case 1:printf("\n Please import the year,month and day which you want tocheck，the year,month and day separation by blank space: ");scanf("%d%d%d",&year,&month,&day);a=x3(year,month,1);if(a==0){printf("Error!Please import again.\n");break;}yueli(year,month,day);break;case 2:printf("\n Please import the year,month and day which you want to check，the year,month and day separation by blank space: ");scanf("%d%d%d",&year,&month,&day);a=x3(year,month,day);if(a==0){printf("Error!Please import again.\n");break;}rili(year,month,day);break;case 3:exit(0);default:printf("Error!Please import again.\n\n");}}2.闰年的判断：计算所输入的年份是否可被4整除，若不能被整除，为平年。

万年历系统——C语言完整版

实验十九：编写一个万年历系统1.设计目的：从实验的角度来看，这次课程设计一方面可以让自己巩固并加深对C语言程序设计知识的理解，掌握和提高C语言编程和程序的基本调试的基本技能，进一步理解和运用结构化程序的思想和方法；另一方面，可以让自己在面对一个全新的问题时，学会如何思考，如何寻找问题的关键，从而提升自己的能力。

2.总体设计：1.、当前页以系统当前日期的月份为准，显示当前月的每一天（显示出日及对应的星期几）；2、当系统日期变到下一个月时，系统自动翻页到下一月。

3.调试与测试：4.源程序清单和执行结果：#include <stdio.h>#include <conio.h>#include <stdlib.h>#include <time.h>int leap(int year ){if ((year %4 == 0) && (year % 100 != 0)|| (year % 400 == 0)){return 1;}return 0;}void show(int year,int month,int date,int sec,int mini,int hour) {const char month_str[][4]={"","Jan","Feb","Mar","Apl", "May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};const int month_day[]={0,31,28,31,30,31,30,31,31,30,31,30,31}; int i,j,wdays,mdays,days;for(i=1,days=0;i<year;i++){if(leap(i)){days += 366;}else{days += 365;}}for(i=1;i<month;i++){if(i==2 && leap(year)){days+=29;}else{days+=month_day[i];}}printf(" %s.%d.%d %d:%d:%d \n",month_str[month],date,year,hour,mini,sec);printf(" 一二三四五六日\n");wdays = days % 7;for( j = 0; j < wdays; j++){printf(" ");}if(month == 2 && leap(year)){mdays=29;}else{mdays= month_day[month];}for(i=1;i<=mdays;i++){if( i > 1 && days % 7 == 0 ){Printf(“\n”);printf("\n");}printf("%4d",i);days=days+1;}printf("\n---------------------------\n\n\n");}void main(){time_t rawtime;struct tm *info;int year,month,date,sec,mini,hour; char ch;time ( &rawtime );info = localtime ( &rawtime );year =info->tm_year + 1900; month =info->tm_mon + 1;date =info->tm_mday;hour =info->tm_hour;mini =info->tm_min;sec =info->tm_sec;while(1){show(year,month,date,sec,mini,hour); printf("↑......上一年\n\n");printf("↓......下一年\n\n");printf("←....前一个月\n\n");printf("→....后一个月\n\n");printf("Esc.......退出\n\n");ch=getch();switch(ch){case 27://Ecsexit(0);case -32://Navigatorch=getch();if(ch==77){//Rightyear+=(month==12)?1:0;month=month%12+1;}else if(ch==75){//Leftyear-=(month==1)?1:0;month=(month-2+12)%12+1;}else if(ch==72) {//Upyear--;}else if(ch==80) {//Downyear++;}system("cls"); }}}。

1.2设计任务及具体要求设计一个小型信息系统,具有信息录入、信息浏览显示、信息删除修改、信息查询等功能，重点解决是查询的实现问题。

利用软件工程中的方法进行系统分析。

学会编制结构清晰、风格良好、数据结构适当的C语言程序，从而具备解决综合性实际问题的能力。

2概要设计2.1该程序可实现的功能主要有以下几点1、输入一个年份，在屏幕上输出该年的年历（包括每月的天数和所对应的星期几），并且在每月的左上角或右上角打印出相应的年份和月份，要求输出界面尽可能整齐、美观，符合年历显示规范。

假定输入的年份在1-9999年之间。

2、输入年月，输出该月的月历。

3、输入年月日，输出距今天还有多少天，是星期几，是否是公历节日。

：4、指定键盘的某些键，用于控制变换不同年、月、日的显示。

即：当前若正在显示2011年的年历，按下键盘“↑”方向键后，年历变为2010年的。
