Implement an assignment operator overloading method. Make sure that: The new data can be copied correctly The old data can be deleted / free correctly. We can assign like A = B = C 实现赋值运算符重载函数,确保: 新的数据可准确地被复制 旧的数据可准确地删除/释放 可进行A = B = C赋值 ...
Also, you will notice that a reference is returned by the assignment operator. This is to allowoperator chaining. You typically see it with primitive types, like this: int a, b, c, d, e; a = b = c = d = e = 42; This is interpreted by the compiler as: a = (b = (c = (...
copy constructor和assignment operator都是成员之间(memberwise copy)的复制(shallow copy)——复制类的每个成员。 面对动态分配内存的问题(dynamically allocated memory),浅复制将会陷入麻烦。因为,指针的浅复制返回的是该指针地址的副本——压根没有对副本分配新的空间。 例子 #include <cstring> #include <cassert> ...
这条线this->operator()不起作用.我只想使用我定义的运算符作为我的类的成员函数A.我得到的错误是:Error 1 error C3867: 'A::operator ()': function call missing argument list; use '&A::operator ()' to create a pointer to member c++ operator-overloading van*_*nna 2012 07-09 4推荐指数...
错误C2440:“正在初始化”:无法从“const wchar_t [12]”转换为“Fstring” 我真的很困惑,我在谷歌上搜索了“重载运算符”,但所有结果都与我用来重载运算符的方式相同。那么为什么这不起作用呢? c++wchar-toperator-overloadingassignment-operator Mor*_*ade ...
