5. Design the class Goldfish, which models a creature that is intelligent enough to remember capacity characters at a time. class Goldfish { public: Goldfish(int capacity); ~Goldfish (); void remember(char c); void forget(); void printMemory() const; // Prints the content of m memory // Clears m_memory using dots('.') private: char *m_memory; // Pointer to memory. // # of chars remembered. // # of chars this fish can remember. int m amount; int m_capacity; }; (a) Define the constructor. Dynamically allocate capacity-many characters to m_memory. Initialize m_memory with dot(' . ')s. If capacity is not positive, then set it to 3 by default. Remember to set m_capacity.

In C++ Declare a Character Pointer and allocate a dynamic array of 22 characters.

In the code segment             Double radius = 4.5;             Const double* ptr = & radius;The ptr is constant, but the data pointed to by the pointer ptr is not constant options:   True   False

What do a pointer and a reference have in common?
