Shape* sarray[] = {new Circle, new Circle, new Circle};
error C2143: syntax error : missing ';' before '}'
error C2059: syntax error : ';'
The following is the full code.
#include
class Shape {
public:
virtual void draw() = 0;
virtual void erase() = 0;
virtual ~Shape() {}
};
class Circle : public Shape {
public:
Circle() {}
~Circle() { std::cout << "Circle::~Circle\n"; }
void draw() { std::cout << "Circle::draw\n";}
void erase() { std::cout << "Circle::eras

r u sure? i don't see anything wrong with the code,
other than there shouldn't be a semicolon after main, but it's no biggie.

Nothing is wrong.
Compiles fine with g++ and VC++2008. Did you have a typo somewhere?

I am not able to duplicate your syntax errors either. But you need release
the memory since you "new" three Circle objects.

You are right. I tried the same code by g++, no error.
But VC++ 6.0 gives this error.

change
Shape* sarray[] = {new Circle, new Circle, new Circle};
to
Shape* sarray[] = {new Circle(), new Circle(), new Circle()};
VC++ 6.0 compiles without errors.
Shape* sarray[] = {new Circle, new Circle, new Circle};
to
Shape* sarray[] = {new Circle(), new Circle(), new Circle()};
VC++ 6.0 compiles without errors.
