Code:

class CommandInterface {
  public:
  void createBank(int a) {};
};

int main()
{
  CommandInterface a;
  typedef void(CommandInterface::*fptr)(int a);
  fptr funcPtr = &CommandInterface::createBank;
  a.*funcPtr("a");
  
  return 0;
}

I can’t compile the code, because I get one of the 2 following errors:

1.error: must use ‘.*’ or ‘->*’ to call pointer-to-member function in ‘funcPtr (...)’, e.g. ‘(... ->* funcPtr) (...)

or

1. Called object type 'fptr' (aka '...') is not a function or function pointer

How can I fix this issue?
