1. using normal object creation: Shape obj; 2. copy ctor: Shape obj2=obj;// or Shape obj3(obj); 3. using new operator;

Code
#include <iostream>
 
using namespace std;
 
class Shape{
public:
        Shape(){cout<<"Shape..."<<endl;}
        Shape(const Shape& obj)
        {
                cout<<"Copy called"<<endl;
        }
        void* operator new(size_t size)
        {
                cout<<"new...."<<endl;
                void* storage=malloc(size);
                if(NULL == storage) {
                        throw "allocation fail : no free memory";
                }
                return storage;
        }
 
        void operator delete (void*){
 
        }
};
 
int main()
{
        Shape obj;
        Shape obj2=obj;
        Shape obj3(obj);
        Shape* ptrShape=new Shape();
        Shape* ptrShapeOver= new Shape();
        return 0;
}

1. Create on stack. i.e. ClassA varA;
2. Create on heap. i.e. ClassA *ptrA = new ClassA;
