随机购买n注彩票，或者手动输入彩票数字，看看你的幸运值如何？
对体彩超级大乐透的前区5个数字和后区2个数字进行区分，前区（1-35），后区（1-12），避免错误输入，避免输入数字超过范围，避免前区或后区中有重复数字，判断获奖情况。

代码如下

#include <iostream>
#include<ctime>
#include<stdlib.h>
#include<vector>
using namespace std;//生成随机数
void produceNum(vector<int> &A);
//检测数字是否存在
bool checkSamenum(vector<int>A,int temp);
//打印数字
void printNum(vector<int> A);
//检测单注前后区中奖数字个数
vector<int> correctNum(vector<int> predictNum,vector<int> chooseNum);
//选择购买数字
void chooseNum(vector<vector<int>>&buyNum);
//保存所有中奖情况
vector<vector<int>> winSum(vector<int> &winNum,vector<vector<int>> buyNum);
//获奖情况
void awards(vector<vector<int>> &winSum);
//随机购买数字
