Question: Take the following program and then add the overloaded cin (>>), cout( < = 0 && c size) { cout < < Invaild cell number.

Take the following program and then add the overloaded cin (>>), cout(<<), the equals (==), the equal (=), and the brackets ( [] ) functions.

Program:

class NumberArray { private: double *arrayPointer; int size; public: // Constructor NumberArray(int); // Destructor ~NumberArray(); // Mutator void setCell(int, double); // Accessor int getCell(int); // getAverage function double getAverage();

// getHighest function double getHighest();

// getLowest function double getLowest(); };
