为何我定义的类不能初始化为NULL

[sillyou]

error C2440: 'initializing' : cannot convert from 'const int' to 'class CMyClass'
No constructor could take the source type, or constructor overload resolution was ambiguous

[bluebohe]

类当然不能初始化成NULL，NULL是给指针用的

[思危]

你的类没有定义以NULL为参数的构造函数

[思危]

class CNuller
{
public:
CNuller();
CNuller(const int n) {p=n;}
~CNuller();

public:
int p;
};

CNuller n1(NULL);
CNuller n2 = NULL;
