There is a homework question which asks what construct in C++ is similar to a Java interface. An interface in Java can be referred to as a pure abstract class, and I know that C++ has abstract classes, but are pure abstract classes something that C++ officially has ?
Maybe from a C++ designer's viewpoint it doesn't, but technically it is possible to create an pure abstract class in C++ by making all methods abstract right?
I looked at this resource but I'm still confused after reading some of the answers...
Yes you can create an abstract class in c++
class A {
public:
A() {};
virtual ~A(){};
virtual void temp() = 0;
};
int main () {
A a; // compiler error
}
class Foo {
public:
Foo();
virtual ~Foo() {};
virtual void bar() = 0;
}
Foo
is a pure abstract class in C++ because it contains the method bar()
which is a pure virtual method.
