Re: [問題] overload operator=
原文恕刪..
#define LEN 200
class A{
public:
int *Array;
int len;
public:
inline int GetLen() { return len; }
inline int* GetArray() { return Array; }
A(int len = LEN) {
Array = new int[len];
}
~A(){
if(Array!=NULL) delete [] Array;
}
A& operator=(const A& obj){
if(this==&obj) return *this;
delete [] Array;
Array = new int[obj.GetLen()];
memcpy(Array, obj.GetArray(), obj.GetLen());
return *this;
}
};
我研讀了相關書籍..
請問改成這種方式是否會有問題？
