1. auto #

Created Monday 18 May 2020

1. Letting the compiler deduce the type;

auto x = 2;
cout << x;	// works - uses predefined rules for int, in this case

2. Auto is homogeneous. 1. If used in a declaration list, will make all the variables the same c++ auto x = 2, y = 'c'; // cannot be different

3. Auto can be used for functions too but they shouldn’t return different types of values(e.g can return an int, or a string etc), **this is the same error. **Python does it though.

auto p(int x)
{
  if(x==1)
      return 1; // returns int
  return "two";	// return string
}

3. auto ignores top-level **consts, **except in references. It just drops them. i.e we will need to do const auto or auto const.
