weak typing
Jump to user comments
programming Strict enforcement of type rules but with
well-defined exceptions or an explicit type-violation
Weak typing is "friendlier" to the programmer than strongtyping, but catches fewer errors at compile time.
C and C++ are weakly typed, as they automatically coerce
many types e.g. ints and floats. E.g.
int a = 5;
float b = a;
They also 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? */
