Abstract Class problem

[Saurabh Gupta]

CMy is a abstract class. As per abstract class definition we can not make any instance of that. But it is not giving any error in MSDEV IDE.

#include <iostream.h>
class CMy
{
public:
CMy(){}
CMy(int i)
{
this->i=i;
};

~CMy()
{
};
virtual void show() const =0;

int i;
};

void show(CMy &myObject)
{
myObject.i = 7;
}

void main(int argc, char* argv[])
{
CMy(9);
show(CMy(6));
}
