构造函数名=delete:让编译器禁止调用某构造函数。 八,参考阅读 《C++新经典》 《C++ Primer》 《C++ Primer Plus》 C++ Constructors: Types and Copy Constructors (programiz.com) Move Constructors in C++ with Examples - GeeksforGeeks 本文参与 腾讯云自媒体同步曝光计划,分享自微信公众号。 原始发表:2023-...
在函数的参数列表后面加上=delete来指出我们希望将它定义为删除的: struct NoCopy { NoCopy() = default; // 使用合成的默认构造函数 NoCopy(const NoCopy&) = delete; // 阻止拷贝 NoCopy &operator=(const NoCopy&) = delete; // 阻止赋值 ~NoCopy() = default; // 使用合成的析构函数 // 其他成...

new and delete In previous versions of the library, the implementation-defined operator new and delete functions were exported from the runtime library DLL (for example, msvcr120.dll). These operator functions are now always statically linked into your binaries, even when using the runtime ...
struct moveable { moveable() = default; moveable(moveable&&) = default; moveable(const moveable&) = delete; }; struct S { S(moveable && m) : m_m(m)//copy constructor deleted {} moveable m_m; }; 若要修复此错误,请改用 std::move: C++ 复制 S(moveable && m) : m_m(std::mov...
