猜数字
小游戏介绍:猜数字游戏是令游戏机随机产生一个100以内的正整数,用户输入一个数对其进行猜测,需要你编写程序自动对其与随机产生的被猜数进行比较,并提示大了,还是小了,相等表示猜到了。如果猜到,则结束程序。
小游戏实现的功能:
1.设置随机数:生成1到100的随机数
2.精美的菜单:让用户明白怎么操作游戏
3.五次猜机会:只有五次猜数字的机会
4.游戏登入页面:输入密码登入小游戏
5.自行选择操作:用户自行选择玩游戏或者退出游戏
首先来到我们的头文件:
#include<iostream>//标准输入输出流
#include<malloc.h>//动态开辟内存
#include<assert.h>//断言
#include <Windows.h>//改变字体颜色
#include<ctime>//使用time函数
#include<conio.h>//使用getch函数
枚举常量:
enum Menu
{
Quit = 0,
Play = 1
};
小游戏的登入系统 :
void menu2()
{
int input = 0, count = 0, i = 0;
char mima[20] = "123";
char shuru[20] = { 0 };
system("color F4");
cout << "\t\t\t **************************************" << endl;
cout << "\t\t\t | *欢迎来到猜数字小游戏* |" << endl;
cout << "\t\t\t | * * |" << endl;
cout << "\t\t\t ------------------------------------ " << endl;
cout<<"请输入登入密码:"<<endl;
while ((count = _getch()) != '\r')
{
if (count == '\b')
{
i--;
cout << "\b \b" << endl;
}
else
{
shuru[i++] = count;
cout<<"*"<<flush; //flush不换行的输出流
}
}
shuru[i++] = '\0';
if (strcmp(mima, shuru) == 0)//比较字符串的大小
{
cout << "\n密码正确,您已进入系统!" << endl;
}
else
{
cout << "密码错误,请重新输入!" << endl;
exit(0);//关闭当前文件
}
system("pause");
system("cls");
}
我们的游戏环节:
void game()
{
int r = rand() % 100 + 1;//生成1到100之间的随机数
int* ptr = (int*)malloc(sizeof(int));
assert(ptr);//判断ptr的动态内存有没有开辟成功
int count = 5;
while (count--)
{
cout << "请输入你喜欢的数字>:" <<endl;
cin >> *ptr;
if (*ptr > r)
{
cout << "你还有" << count << "次机会" << endl;
cout << "猜大啦!" << endl;
}
else
{
cout << "你还有" << count << "次机会" << endl;
cout << "猜小啦!" << endl;
}
if (*ptr == r)
{
cout << "恭喜你,猜对了!" << endl;
break;
}
if (count == 0)
{
cout << "很遗憾,失败了,正确的值为" << r << endl;
}
}
free(ptr);//释放空间
ptr = NULL;
}
我们的操作菜单:
void menu1()
{
system("color F4");
cout << "|----------------------------------|" << endl;
cout << "|----------*猜数字游戏*------------|" << endl;
cout << "|------------1.Play----------------|" << endl;
cout << "|------------0.Quit----------------|" << endl;
cout << "|----------------------------------|" << endl;
}
我们的main函数:
int main()
{
menu2();
srand((unsigned int)time(NULL));//添加随机数种子,利用当前时间作为随机数,防止每次随机数都一样
int* input = (int*)malloc(sizeof(int));
assert(input);//判断input的动态内存有没有开辟成功
do {
system("cls");//清空控制台
menu1();
cout << "请输入当前操作:" << endl;
cin >> *input;
switch (*input)
{
case Quit://枚举类型美化选项
cout << "--------*您已退出游戏*--------" << endl;
system("pause");
break;
case Play:
game();
system("pause");
break;
default:
cout << "-----------*输入错误,重新输入*-----------" << endl;
cin >> *input;
system("pause");
}
} while (*input);
free(input);//释放空间
input = NULL;
return 0;
}
以下就是我们猜数字小游戏的整个代码啦:
#include<iostream> #include<malloc.h> #include<assert.h> #include <Windows.h> #include<ctime> #include<conio.h> using namespace std; enum Menu { Quit = 0, Play = 1 }; void menu2() { int input = 0, count = 0, i = 0; char mima[20] = "123"; char shuru[20] = { 0 }; system("color F4"); cout << "\t\t\t **************************************" << endl; cout << "\t\t\t | *欢迎来到猜数字小游戏* |" << endl; cout << "\t\t\t | * * |" << endl; cout << "\t\t\t ------------------------------------ " << endl; cout<<"请输入登入密码:"<<endl; while ((count = _getch()) != '\r') { if (count == '\b') { i--; cout << "\b \b" << endl; } else { shuru[i++] = count; cout<<"*"<<flush; } } shuru[i++] = '\0'; if (strcmp(mima, shuru) == 0) { cout << "\n密码正确,您已进入系统!" << endl; } else { cout << "密码错误,请重新输入!" << endl; exit(0); } system("pause"); system("cls"); } void game() { int r = rand() % 100 + 1; int* ptr = (int*)malloc(sizeof(int)); assert(ptr); int count = 5; while (count--) { cout << "请输入你喜欢的数字>:" <<endl; cin >> *ptr; if (*ptr > r) { cout << "你还有" << count << "次机会" << endl; cout << "猜大啦!" << endl; } else { cout << "你还有" << count << "次机会" << endl; cout << "猜小啦!" << endl; } if (*ptr == r) { cout << "恭喜你,猜对了!" << endl; break; } if (count == 0) { cout << "很遗憾,失败了,正确的值为" << r << endl; } } free(ptr); ptr = NULL; } void menu1() { system("color F4"); cout << "|----------------------------------|" << endl; cout << "|----------*猜数字游戏*------------|" << endl; cout << "|------------1.Play----------------|" << endl; cout << "|------------0.Quit----------------|" << endl; cout << "|----------------------------------|" << endl; } int main() { menu2(); srand((unsigned int)time(NULL)); int* input = (int*)malloc(sizeof(int)); assert(input); do { system("cls"); menu1(); cout << "请输入当前操作:" << endl; cin >> *input; switch (*input) { case Quit: cout << "--------*您已退出游戏*--------" << endl; system("pause"); break; case Play: game(); system("pause"); break; default: cout << "-----------*输入错误,重新输入*-----------" << endl; cin >> *input; system("pause"); } } while (*input); free(input); input = NULL; return 0; }
