Compliant Solution (static storage duration)
Exceptions
MEM31-EX1: It is permissible not to free memory that is used throughout the lifetime of the program. The following code example illustrates a pointer In this compliant solution, the pointer object that stores the return value from malloc() that is stored in a static variable of static storage duration.
