[置顶] operator overloading(操作符重载，运算符重载)运算符重载,浅拷贝(logical copy) ,vs, 深拷贝(physical copy)

operator overloading(操作符重载,运算符重载) 所谓重载就是重新赋予新的意义,之前我们已经学过函数重载,函数重载的要求是函数名相同,函数的参数列表不同(个数或者参数类型).操作符重载也叫运算符重载,顾名思义,运算符重载就是给运算符赋予新的意义,新的使命. 1.首先要说的是,c++中不允许用户自定义运算符,只允许程序员重载运算符. 2.那些运算符可以重载?c++中绝大部分与运算符允许重载,不能重载的运算符有5类, (1) . (成员访问运算符).(2).* (成员指针运算符)(…
