c++ getClass()?

[cmk128]

Hi
How can i do something like Java:

if (str.getClass()==String.class){
}


i found that, this syntax has error in g++:

if (typeof(a) == typeof(b)){
}

thanks

try typeid.

Try

if (typeid(a) == typeid(b)){

Don't forget to '#include <typeinfo>'

class A { public: virtual ~A() { } };
class B : public A { };

int main()
{
A a, b;
assert( typeid( a ) == typeid( b ) );
B c;
assert( typeid( a ) != typeid( c ) );
}

Frankly though, if you need to do the above, then you probably have a design problem.

class A { public: virtual ~A() { } };
class B : public A { };

int main()
{
A a, b;
assert( typeid( a ) == typeid( b ) );
B c;
assert( typeid( a ) != typeid( c ) );
}

thank you so much
