Coding standards

Code examples

The following code example fails the check and will give a warning:

struct A {
  virtual void foo(int a);
};

struct B : public A {
  void foo(int b) override;
};

The following code example passes the check and will not give a warning about this issue:

struct A {
  virtual void foo(int a);
};

struct B : public A {
  void foo(int a) override;
};

void B::foo(int) {
  // Do nothing
}
