Weak typing in C allows type casting memory to different types. Because the internal representation of most types is system dependent, applying operations intended for data of one type to data of a different type will likely yield non-portable code and produce unexpected results.
Non-Compliant Code Example (Integers vs.

Floating-Point Numbers)
The following non-compliant code demonstrates the perils of operating on data of incompatible types. An attempt is made to increment an integer type cast to a floating point type, and a floating point cast to an integer type.
