一，声明

被人水平有限，开源只是为了分享。勿喷！！！还请大佬指点。

二，代码

int Options_2; //第二个用户选项 (选择难度) 
long long answer;//用户的答案

{srand(static_cast<unsigned int>(time(NULL))); // 随机生成种子a = rand() % 10;b = rand() % 10;
} void plan_2()

}void plan_3()
{srand(static_cast<unsigned int>(time(NULL))); // 随机生成种子a = rand() % 1000;b = rand() % 1000;
}void division_1()
{srand(static_cast<unsigned int>(time(NULL))); // 随机生成种子a = rand() % 10;b = rand() % 9 + 1;//生成1到9的随机数 
} void division_2()
