用C语言写一个订座系统

函数声明部分写出该系统的主要功能以及结构体

typedef struct SeatPosition{

int num;

int flage;

char name[20];

}Seat;

void menu();//主菜单

void SelectFunction(Seat *seat);//选择功能

void ShowAll(Seat * seat);//显示所有座位

void ShowNum(Seat * seat);//显示未预定的座位编号

void AddSeat(Seat * seat);//添加一个位子

void DeleteSeat(Seat * seat);//删除一个位子

void Empty(Seat *seat);//清空

void Exit();//退出

函数实现部分

include “test.h”

include

pragma mark —2

char Delete(char *string)

{

printf(“请输入一串字符串”);

scanf(“%s”,string);

gets(string);

while (string != ‘\0’) {

if (*string == ’ ‘) {

string = (string+1);

string–;

}}printf(“%s”,string);

return *string;

}

pragma mark —3

void menu()

{

printf(“*欢迎来到万达电影订座系统**\n”);

printf(“功能如下：\n”);

printf(“1.所有座位的信息\n”);

printf(“2.未预定的座位编号\n”);

printf(“3.添加一个座位\n”);

printf(“4.删除一个座位\n”);

主函数定义该结构体的内容，以及调用函数

pragma mark –3

Seat seat[12] = {
{1,1,"刘"},
{2,1,"关"},
{3,1,"张"},
{4,0," "},
{5,0," "},
{6,0," "},
{7,0," "},
{8,0," "},
{9,0," "},
{10,0," "},
{11,0," "},
{12,0," "}};
SelectFunction(seat);
return 0;

}
