[C++筆記] 拷貝建構式(Copy Constructor) & 複製指派運算子(Copy Assignment Operator)

很容易搞混的兩種運用

比較

例子

Copy Constructor

T::T(const T& t)
{
     hours = t.hours;
     minutes = t.minutes;
     len = t.len;
     str = new char [len+1];
     //this is why we should implement the copy constructor
}

Copy Assignment Operator

T& T::operator=(const T& t)
{
     if(this == &t)//check if the sample address(it means the sample variable)
          return *this;
     delete []str;
     //you also can check the string.len if not enough
     len = new char [len+1];
     std:strcpy(str, t.str);
     hours = t.hours;
     minutes = t.minutes;
     return *this;
}
