前言

近期有朋友双色球中了个小奖，所以临时兴起，写了个模拟双色球系统玩玩，购买规则、开奖以及中奖等级均模仿现实规则，小部分玩法自定。

开发此系统需要熟悉 C 语言指针的使用、结构体的设计；如果能轻松的写出来，说明你C语言掌握的已经算是相对熟练了，工作中应对中小型项目已经足够了，话不多说，直接开整。

1. 设定系统架构

首先，制定该系统需要实现的具体功能、玩法，初步制定好目标后，构思结构体如何设定才能更便捷的访问数据，把功能细分化，模块化，尽量减少重复代码，一个好的初步结构，会让整个过程事半功倍，所以必须构思好基本盘。

1.1 我的设计目标

菜单功能：1.买球 2.兑奖信息 3.开奖历史 4.查余额 5.退出；

玩法：①自选或者机选号码，

②红、蓝球复式购买或者正常飞复式购买，一注花费2rmb，

③购买倍数；

数据录入：自选的话需要使用键盘输入号码，第一次玩还需要输入购买者姓名；

号码输入完成后，显示购买的组合信息以及购买金额；

另外，还模拟了50个机器人购买；

开奖：购买完成后直接跳入开奖环节；

开奖结束后会显示中奖人信息、中奖等级；

中奖等级：分为一到六级，一级最高；

兑奖信息：显示购买信息，以及中奖等级；

开奖历史：显示历史开奖号码；

余额查询：显示余额信息（开局送10W余额）；

退出：释放申请的内存，并退出进程。

2. 系统程序设计

2.1 结构体设计

ROBOT_SIM：定义模拟机器人的数量；enum枚举中奖等级和复式买法；

struct _buy_method结构体汇总买法规则；

struct _data结构体存储号码数据，里面有个next指针变量，串联球号组合数据；

struct _message结构体表示个人购买的信息存储；

struct _win_mess结构体链接所有中奖者信息；

struct _shop_history 结构体表示开奖历史信息；

struct _shop_message结构体表示买球者以及系统的所有信息。

#define ROBOT_SIM  50   //模拟机器人typedef enum _method {MUL_NONE = 0,MUL_RED  = 1,   //红球复式MUL_BLUE,       //蓝球复式MUL_ALL,        //红蓝复式
}method_t;typedef enum _level {LEVEL_NONE = 0,LEVEL_ONE  = 1,     //6+1: 一等奖  LEVEL_TWO,          //6+0LEVEL_THREE,        //5+1LEVEL_FOUR,         //5+0 || 4+1LEVEL_FIVE,         //4+0 || 3+1LEVEL_SIX,          //>0
}level_t;typedef enum _money {RMB_NONE    =0,RMB_5       =5,RMB_10      =10,RMB_200     = 200,RMB_3K      = 3000,RMB_500W    = 5000000,RMB_1KW     = 10000000,
}money_t;typedef struct _buy_method {unsigned int select;         //0:机选  1:自选method_t mul;                //复式买法unsigned int num_count[3];   //[0]:红球数量,[1]:蓝球数量,[2]组合数量unsigned int bet;            //倍数
}buy_method_t;typedef struct _data {unsigned int data[7];struct _data *next;
}data_t;typedef struct _message {char *name;                 //购买者姓名buy_method_t method;        //玩法data_t data;                //购买号码数据unsigned int money;         //花费金额unsigned int remain_money;  //剩余金额level_t win_level;          //中奖等级
}message_t;typedef struct _win_mess {char *win_name;             //中奖人名level_t win_level;          //中奖等级struct _win_mess *next;
}win_mess_t;typedef struct _shop_history {unsigned int date_no;       //开奖期数unsigned int result[7];     //开奖结果win_mess_t win;             //中奖名单struct _shop_history *next;
}shop_history_t;typedef struct _shop_message {message_t all_message[1+ROBOT_SIM];     //顾客购买信息，模拟50人购买shop_history_t history;                 //开奖历史
}shop_message_t;

2.1 main函数

定义一个struct _shop_message结构体变量，汇总所有信息，并初始化该变量；

menu_mode：通过键盘键入菜单功能，然后再进入功能函数去执行；

总之，main函数中不要篇幅太长，太乱，把功能细分化、模块化，就好处理了。

void main()
{char menu_mode ;shop_message_t message;shop_message_t *mess_p = &message;init_struct_data(mess_p);while(1){menu_mode = system_menu();switch (menu_mode){case 1:shop_guide_system(mess_p);break;case 2:show_self_ball_result(mess_p);break;case 3:show_ball_history(mess_p);break;case 4:exit_free_memory(mess_p);break;default:printf("error menu mode !\n");break;}}
}

2.2 功能函数

其实功能函数这块基本都是指针的运用，没啥好说的，懂的都懂，后面会附上所有代码（仅供参考）；其中需要说的地方就是，复式买法会构成很多种组合，这些组合数据需要怎么去计算呢？

那么就涉及到组合算法了，这里讲解下我的基本思路：由于有红球复式和蓝球复式的组合买法，我采取分别计算组合数的方法，先计算红球复式的所有组合数据（使用到了递归函数），然后在红球的组合数据中添加蓝球数据。举例，假如10个红球复式，2个蓝球复式，红球组合数就是10个选6个组合数据，就有210组数据，然后每组红球添加一个蓝球数据，添加两组，总共就420组数据了。代码如下：

/*************   红球组合   ****************/
void red_data_comb(message_t *mess,int red_data[],int temp_data[],int top)
{data_t *data_p = NULL;data_t *data_p1 = NULL;int i = 0,j = 0;if(top > mess->method.num_count[0]) {return;}if(red_data_index == 6) {data_p = (data_t *)&mess->data;if(mess->data.data[0] == 0) {      for(i = 0; i < 6; i++){data_p->data[i] = temp_data[i];}data_p->next = NULL;}else {while(data_p->next != NULL) {data_p = data_p->next;             }data_p1 = data_p;data_p = (data_t *)malloc(sizeof(data_t));data_p1->next = data_p;for(j = 0; j < 6; j++) {data_p->data[j] = temp_data[j];}data_p->next = NULL;}return;}temp_data[red_data_index++] = red_data[top];red_data_comb(mess,red_data,temp_data,top+1);red_data_index--;red_data_comb(mess,red_data,temp_data,top+1);
}/************   红+蓝组合   ************/
void blue_data_comb(message_t *mess,int blue_data[])
{data_t *data_p = NULL;data_t *data_p1 = NULL;data_t *data_p2 = NULL;int red_comb_count = 0;int j = 0;int k = 0;if(mess->data.data[0] == 0){return;}data_p = (data_t *)&mess->data;data_p2 = data_p;for(int i = 0; i < mess->method.num_count[1]; i++){if(i == 0) {while(data_p->next != NULL) {data_p->data[6] = blue_data[i];red_comb_count++;data_p = data_p->next;}data_p->data[6] = blue_data[i];red_comb_count++;data_p1 = data_p;}else {for(j = 0; j < red_comb_count; j++) {data_p = (data_t *)malloc(sizeof(data_t));data_p1->next = data_p;data_p1 = data_p;for(k = 0; k < 7; k++) {if(k < 6){data_p->data[k] = data_p2->data[k];}else {data_p->data[k] = blue_data[i];data_p->next = NULL;data_p2 = data_p2->next;}    }}data_p2 = (data_t *)&mess->data;}}
}/***********   组合号码   ************/
void comb_data(message_t *mess,int red_data[],int blue_data[])
{int temp_data[6] = {0};red_data_comb(mess,red_data,temp_data,0);blue_data_comb(mess,blue_data);
}

2.2.1 组合算法参考

int cur_index = 0;
int array[7]={1,2,3,4,5,6,7};
int data[7];void comb(int index, int n, int m)
{int i = 0;if (index > n)return;if (cur_index == m) {for (i = 0; i < m; i++) {printf("%d", data[i]);}printf("\t");return ;}data[cur_index++] = array[index];comb(index+1, n, m);cur_index--;comb(index+1, n, m);
}

2.3 数据链表

组合数据是通过链表的方式一组一组链接起来的，每当多一个组合数据，就需要为data申请内存空间。菜单功能选择 1，买球前，判断之前是否有为存储个人数据申请过内存，如果有就先释放之前申请的空间，重新初始化data数据；假如购买前不释放掉内存，多玩几次申请的内存将会逐渐庞大。

/************  初始化购买数据  *************/
void clean_self_ball_data(message_t *per_mess)
{int i = 0;data_t *data_p = NULL;data_t *data_p1 = NULL;data_p = (data_t *)&per_mess->data;while(1) {for(i = 0;i < 7; i++){data_p->data[i] = 0;}data_p = data_p->next;if(data_p == NULL) {break;}if(data_p->next != NULL) {data_p1 = data_p->next;free(data_p);data_p = data_p1;}else {free(data_p);    per_mess->data.next = NULL;break;}}
}

2.4 总代码示例

代码仅供参考，代码从0到1，花了周末两天寥寥草草赶出来的，可能存在着一些问题，有些重复性代码，不喜勿喷。

3. 代码测试结果

输入信息后按击确认键进入下一步，测试的时候尽量复式数填少一点，不然组合数过大，申请的内存占用大；退出进程的时候，菜单功能输入数字4，会释放申请的内存再退出进程。
