c++ - 错误 : qualifiers dropped in binding reference of type string to initializer of type const string

Question

标题

class Player {
protected:
    int age;
    string name;

public:
    int getAge();
    string& getName() const;

定义

string& Player::getName() const
{
    return name;
}

使用 getName() 函数时出现以下错误:

error: qualifiers dropped in binding reference of type string to initializer of type const string

我该如何修复它并使其正常工作？

Answer 1

为了使其作为const 可执行，返回类型需要是const&

const string& Player::getName() const
{
    return name;
}
