请用C++制作一个switch游戏

好的，我可以回答这个问题。以下是一个简单的 switch 游戏的 C 代码示例：

#include <stdio.h>

int main() {
int choice;

printf("Welcome to the Switch Game!\n");
printf("Choose a number between 1 and 3:\n");
scanf("%d", &choice);

switch (choice) {
case 1:
printf("You chose option 1.\n");
break;
case 2:
printf("You chose option 2.\n");
break;
case 3:
printf("You chose option 3.\n");
break;
default:
printf("Invalid choice.\n");
break;
}

return ;
}

这个程序会提示用户输入一个数字，然后根据用户的选择输出不同的结果。
