怎么用C加加写一段选择游戏难度的程序代码

#include using namespace std;

int main(){ int level; cout<<"请选择游戏难度：\n1.简单\n2.普通\n3.困难\n"; cin>>level; switch(level){ case 1: cout<<"您选择了简单难度"<<endl; break; case 2: cout<<"您选择了普通难度"<<endl; break; case 3: cout<<"您选择了困难难度"<<endl; break; default: cout<<"您输入的难度有误，请重新输入！"<<endl; break; } return 0; }
