C++都是string 如何将其中一个string 赋值给另外一个？

Question

class Stu{
public:
Stu()
{
name[20] = {0};
addr[100] = {0};
num = "\0";
score = 0.0;
sex = 'f';
}
Stu(char Name[], char Addr[], string Num, double Score, char Sex)
{
strcpy(name, Name);
strcpy(addr, Addr);
strcpy(num, Num); //这里提示我错误，但是我不知道除了这个还能写什么？
score = Score;
sex = Sex;
}
}
//错误是这样的： [Error] cannot convert 'std::string {aka std::basic_string}' to 'char*' for argument '1' to 'char* strcpy(char*, const char*)'

Answer 1

class Stu{
public:
Stu()
{
name[20] = {0};
addr[100] = {0};
num[10] = {0}
score = 0.0;
sex = 'f';
}
Stu(char Name[], char Addr[], char Num[], double Score, char Sex)
{
strcpy(name, Name);
strcpy(addr, Addr);
strcpy(num, Num);
score = Score;
sex = Sex;
}

    我改用数组倒是可以
