求助C语言的猜数字游戏

Question

C语言课程设计要求

1、 课程设计目的
1、 掌握用C语言进行程序设计的基本方法 。
2、 熟练掌握window控制台应用程序的编写。
3、 初步完成一个应用程序的设计、编码、调试，了解程序设计过程，锻炼实际应用能力。
2、 设计题目及内容
猜数字游戏：
计算机随机生成没有重复的n个数，由用户从键盘输入要猜测的数。每猜一次，电脑给出提示信息。如果用户输入的数跟计算机生成的数，数值和位置都完全相等，则胜出。
基本功能要求：
1. 随机生成没有重复的4个数。（每个数字在0-9范围内）。
2. 用户从键盘输入4个不重复的数，程序能对用户输入的数与随机生成的数进行匹配，并给出提示信息：“有 x个数数值和位置都相同！有 y个数数值相同，但位置不同。”
3. 控制用户的尝试次数为10次。
4. 计算、输出并保存用户的得分，计分规则：总分是100分，每失败一次扣10分。
5. 有操作菜单，能根据不同选择运行不同功能：
1：开始游戏！
2：查看上次成绩！
3：输出帮助信息！
0：退出程序！
扩展功能要求：
1. 对用户输入的数字进行检查，如果用户输入重复的数，给出提示，要求重新输入。
2. 能对游戏进行设置：在操作菜单中增加相应的选项：“4：系统设置”。
（1） 修改要猜的数字的个数n，根据修改后的n值，计算机可随机生成n个数，用户进行n个数的猜测游戏。
（2） 修改可以尝试的次数。
3. 若游戏胜出且成绩在前五名，可输入并记录对应的用户姓名，并添加到积分榜中。操作菜单中相应选项改为“2：积分榜！”，用于把积分榜中保存的前五名成绩及用户姓名显示出来。
4. 能对积分榜的成绩进行排序和输出。
提示：（1）生成一个0~9的随机数，使用rand函数：
#include
#include //使用rand函数必须使用此头文件
#include
int main()
{​int a;
​ ​srand(time(0)); //生成一个种子。整个程序只写一次即可。
​ ​a=rand()%10; //生成一个随机数。
​ printf("%d\n",a);
​ ​return 0;
}
（2）保证生成的n个数不重复：
可用数组记录生成的数，每生成一个数，要与之前已经生成的进行比较，如果有相同的​重新生成，直到不相同。
