1.cin中文乱码的解决

2.代码实践

# include "iostream"
# include "windows.h"
using namespace std;int main()
{SetConsoleOutputCP(CP_UTF8);string str;cin >> str;cout << str << endl;return 0;
}

注意，勾选之后以后也不需要再加 SetConsoleOutputCP(CP_UTF8);了

3.总结

4.练习题

# include "iostream"
using namespace std;int main()
{string name;double height;int age;cout << "请输入您的姓名：" << endl;cin >> name;cout << "请输入您的身高（CM）：" << endl;cin >> height;cout << "请输入您的年龄：" << endl;cin >> age;cout << "-------------" << endl;cout << "信息输入完成，您的信息如下：\n姓名：" + name + "\n身高：" + to_string(height) + "cm\n年龄：" + to_string(age) << endl;return 0;
}
