Hmm, I thought that C++ was strongly typed, so I looked around a bit.
For me, strong typing means that there is a strict enforcement of type
rules, with no exceptions, and that everything has one type and one
type only, that cannot change during the lifetime.
C++ violates this principle only because of the coercion for numeric
values, E.g.
int a = 5;
float b = a;
and because they allow ignore typedefs for the purposes of type
comparison; for example the following is allowed, which would probably
be disallowed in a strongly typed language:
typedef int Date; /* Type to represent a date */
Date a = 12345;
int b = a; /* What does the coder intend? */
