不能适当地使操作员“新"操作超载.和“删除"?

问题描述

提前非常感谢.
我正在DevC ++环境中从事C ++项目.

我正在尝试重载"new"和"delete"运算符，但无法调用这些重载的运算符.您能帮我确定我在哪里做错吗?

Hi,

Thanks very much in advance.
I am working on C++ project in DevC++ environment.

I am trying to overload "new" and "delete" operators but I am unable to call those overloaded operators. Can you please help me identifying where am I making mistake??

void* operator new (size_t , int )// working
{
      cout<<"This is overloaded-new operator"<<endl;
}

void operator delete (void* pointer, int iData)// working
{
     cout<<"This is overloaded-delete operator"<<endl;
}

void main()
{
// as per my understanding following should call overloaded operators
// following gives error: invalid conversion from int to void*
//          initializing argument 2 of void* operator new[](size_t, void*)
void* chObjNew = new(10)char[10];
// following error: type int argument given to delete expected pointer
     delete(chObjNew, 10) ;
}

推荐答案

void* operator new[](size_t t)
{
     // ...
}

并类似地删除

and similarly delete

void operator delete[](void* ptr
{
   // .....
}

::operator delete(chObjNew, 10);

希望这会有所帮助，
