C++ 中的移动语义是 C 所缺少的吗

移动语义在 C++ 中的引入

cpp
class MyArray {
public:
    MyArray(int size) : m_size(size), m_data(new int[size]) {}
    ~MyArray() { delete[] m_data; }
    // 移动构造函数
    MyArray(MyArray&& other) : m_size(other.m_size), m_data(other.m_data) {
        other.m_size = 0;
        other.m_data = nullptr;
    }
    // 移动赋值运算符
    MyArray& operator=(MyArray&& other) {
        if (this != &other) {
            delete[] m_data;
            m_size = other.m_size;
            m_data = other.m_data;
            other.m_size = 0;
            other.m_data = nullptr;
        }
        return *this;
    }
private:
    int m_size;
    int* m_data;
};
