C语言课程设计之快递包裹系统

 实现的功能

1.对于整个系统的加密，即设置密码，主要用到了字符串的对比；

2.界面设计；

3.基本信息的增删改查；

4.单号排序；

5.打印。

 这是一些用到的函数声明

//函数声明
void password(); //系统加密
void menu();     //菜单栏
void establish();//输入信息
void revamp();   //修改信息
void del();      //删除信息
void save();     //保存信息
void search();   //查询信息
void sort();     //单号排序
void read();     //读取信息
void sum();      //统计包裹数
void print();    //打印报表typedef struct Express
{char sender[100];//寄件方char receiver[100];//收件方char senderaddress[100];//寄件方地址char receiveraddress[100];//收件方地址char tracknumber[100];//快递单号char phonenumber1[100];//寄件方电话号码char phonenumber2[100];//收件方电话号码
}express;

 加密模块

int main()
{   password();        //系统加密system("color f3");//改变窗口背景及字体颜色menu();
}void password()//系统加密
{char a[100],b[100]="666666";printf("————————快递包裹系统V1.0————————\n");printf("请输入登录密码：");scanf("%s",&a);if(strcmp(a,b)==0){printf("登陆成功！\n");system("pause");//暂停}else{  printf("密码输入错误！无法进入系统！\n");exit(0);}
}

界面菜单 

void menu() //菜单栏
{   int n;while(1){ system("cls");//清屏puts("\t 快递包裹系统V1.0");puts("***************MENU**************");puts("*\t   1.输入信息\t\t*");puts("*\t   2.修改信息\t\t*");puts("*\t   3.删除信息\t\t*");puts("*\t   4.保存信息\t\t*");puts("*\t   5.查询信息\t\t*");puts("*\t   6.单号排序\t\t*");puts("*\t   7.读取信息\t\t*");puts("*\t   8.统计数量\t\t*");puts("*\t   9.打印报表\t\t*");puts("*\t   0.退出\t\t*");puts("*********************************");puts("请输入序号：");	n=getchar();//从键盘输入一个字符switch(n){case'1':establish();break;//输入信息case'2':revamp();break;   //修改信息case'3':del();break;      //删除信息case'4':save();break;     //保存信息case'5':search();break;   //查询信息case'6':sort();break;	    //单号排序case'7':read();break;	    //读取信息case'8':sum();break;	    //统计数量case'9':print();break;	//打印报表case'0':exit(0);          //退出}}
}

对于信息增删查改

void establish()//输入信息
{node *pnewnode=(node*)malloc(sizeof(node));pnewnode->next=NULL;if(head==NULL){head=pnewnode;}else{pnewnode->next=head;head=pnewnode;}printf("请输入相关信息\n");printf("寄件方姓名：");scanf("%s",pnewnode->express.sender);printf("寄件方电话号码：");scanf("%s",pnewnode->express.phonenumber1);printf("寄件方地址：");scanf("%s",pnewnode->express.senderaddress);printf("收件方姓名：");scanf("%s",pnewnode->express.receiver);printf("收件方电话号码：");scanf("%s",pnewnode->express.phonenumber2);printf("收件方地址：");scanf("%s",pnewnode->express.receiveraddress);printf("快递单号：");scanf("%s",pnewnode->express.tracknumber);printf("输入成功\n");system("pause");//暂停system("cls");//清屏}void revamp()//修改信息
{node *p1=head;char tracknumber[100],ch;
int flog=0;
printf("\t\t\t\t*修改数据*\n");
printf("===========================================================================\n");
printf("请输入将要修改包裹单号：");
scanf("%s",tracknumber);
while(p1!=NULL)
{ if(strcmp(tracknumber,p1->express.tracknumber)==0)
{printf("该包裹基本信息\n");printf("寄件方姓名：%s\n",p1->express.sender);printf("寄件方电话号码：%s\n",p1->express.phonenumber1);printf("寄件方地址：%s\n",p1->express.senderaddress);printf("收件方姓名：%s\n",p1->express.receiver);printf("收件方电话号码：%s\n",p1->express.phonenumber2);printf("收件方地址：%s\n",p1->express.receiveraddress);printf("快递单号：%s\n",p1->express.tracknumber);flog=1;printf("\n请选择要修改的信息\n");printf("\t1.寄件方姓名\t2.寄件方电话号码\t3.寄件方地址\t4.收件方姓名\n");printf("\t5.收件方电话号码\t6.收件方地址\t7.快递单号\n");printf("您的选择是(1~7):");scanf("%s",&ch);switch(ch){case'1':printf("请输入修改之后的内容：\n寄件方姓名：");scanf("%s",p1->express.sender);printf("\n修改成功!\n");printf("===========================================================================\n");break;case'2':printf("寄件方电话号码：");scanf("%s",p1->express.phonenumber1);printf("\n修改成功!\n");printf("===========================================================================\n");break;case'3':printf("寄件方地址：");scanf("%s",p1->express.senderaddress);printf("\n修改成功!\n");printf("===========================================================================\n");break;case'4':printf("收件方姓名：");scanf("%s",p1->express.receiver);printf("\n修改成功!\n");printf("===========================================================================\n");break;case'5':printf("收件方电话号码：");scanf("%s",p1->express.phonenumber2);printf("\n修改成功!\n");printf("===========================================================================\n");break;case'6':printf("收件方地址：");scanf("%s",p1->express.receiveraddress);printf("\n修改成功!\n");printf("===========================================================================\n");break;case'7':printf("快递单号：");scanf("%s",p1->express.tracknumber);printf("\n修改成功!\n");printf("===========================================================================\n");break;}}p1=p1->next;
}if(flog==0){printf("没有找到该人的信息!\n");}system("pause");//暂停system("cls");//清屏
}void del()//删除信息
{node *p1,*p2;char tracknumber[100];int flog=1;printf("请输入要删除的快递单号:");scanf("%s",tracknumber);p2=p1=head;while(p1!=NULL&&flog){if(strcmp(tracknumber,p1->express.tracknumber)==0)//比较字符{printf("您要找到的数据\n");printf("寄件方姓名：%s\n",p1->express.sender);printf("寄件方电话号码：%s\n",p1->express.phonenumber1);printf("寄件方地址：%s\n",p1->express.senderaddress);printf("收件方姓名：%s\n",p1->express.receiver);printf("收件方电话号码：%s\n",p1->express.phonenumber2);printf("收件方地址：%s\n",p1->express.receiveraddress);printf("快递单号：%s\n",p1->express.tracknumber);if(p1==head){head=p1->next;free(p1);}else{p2->next=p1->next;free(p1);}flog=0;printf("删除成功\n");}p1=p1->next;}if(flog){printf("未有此包裹！");}system("pause");system("cls");
}void save()//保存信息
{  FILE *fp=fopen("file.dat","w");system("cls");if(fp==NULL){printf("打开文件失败");return;}p=head;while(p!=NULL){fwrite(&p->express,1,sizeof(Express),fp);p=p->next;}fclose(fp);printf("\n数据保存成功\n");system("pause");system("cls");}void search()//根据快递单号查询信息
{char tracknumber[100];int flog=1;node *p=NULL;p=head;printf("请输入快递单号：");scanf("%s",tracknumber);while(p!=NULL)
{if(strcmp(tracknumber,p->express.tracknumber)==0)//比较字符{printf("您要找到的数据\n");printf("寄件方姓名：%s\n",p->express.sender);printf("寄件方电话号码：%s\n",p->express.phonenumber1);printf("寄件方地址：%s\n",p->express.senderaddress);printf("收件方姓名：%s\n",p->express.receiver);printf("收件方电话号码：%s\n",p->express.phonenumber2);printf("收件方地址：%s\n",p->express.receiveraddress);printf("快递单号：%s\n",p->express.tracknumber);flog=0;}p=p->next;
}
if(flog)
{printf("查无此包裹！\n");
}system("pause");//暂停system("cls");//清屏
}

以上就是核心功能的部分，对于此课程设计，还有美中不足的是，对于收录的快递单号没有进行查重，于是乎，在面对庞大的信息量时，当人为的记不住，就会导致错误的出现，希望读者能够完善此系统。最后附上完整的代码——
