Given the following class declaration (with prototypes): class NumberArray { private: double *aPtr; // pointer to a dynamic array of floating-point numbers int arraySize; // size of the array public: NumberArray(int size, double value); // 2-parameter constructor // allocates array and sets all numbers to value void print() const; void setValue(double value); }; Assume NumberArray has been implemented. Consider the following program segment and rewrite the class declaration to address the issues indentified in a-d. 1: NumberArray first(3,10.5), second(5,6.9); 2: NumberArray third = second; 3: second = first; 4: NumberArray array[10]; Rewrite the entire class declaration. Add the necessary member prototypes to correct the following problems: a) In Line 2 the behavior is not what we expect. Identify what needs to be added to the class for the code to behave properly and add the prototype to the class declaration with comment. b) In Line 3 the behavior is not what we expect. Identify what needs to be added to the class for the code to behave properly and add the prototype to the class declaration with comment. c) In Line 4 a compile-time error will occur. Identify what needs to be added to the class for the code to compile and add the prototype to the class declaration with comment. d) Finally, identify what needs to be added to the class to free dynamic memory and add the prototype to the class declaration with comment.

Question

Given the following class declaration (with prototypes):

class NumberArray
{
private:
double *aPtr; // pointer to a dynamic array of floating-point numbers
int arraySize; // size of the array

public:
NumberArray(int size, double value); // 2-parameter constructor
// allocates array and sets all numbers to value

void print() const;
void setValue(double value);
};

Assume NumberArray has been implemented.

Consider the following program segment and rewrite the class declaration to address the issues indentified in a-d.

1:   NumberArray first(3,10.5), second(5,6.9);
2:   NumberArray third = second;
3: second = first;
4:   NumberArray array[10];

Rewrite the entire class declaration. Add the necessary member prototypes to correct the following problems:

a) In Line 2 the behavior is not what we expect. Identify what needs to be added to the class for the code to behave properly and add the prototype to the class declaration with comment.
b) In Line 3 the behavior is not what we expect. Identify what needs to be added to the class for the code to behave properly and add the prototype to the class declaration with comment.
c) In Line 4 a compile-time error will occur. Identify what needs to be added to the class for the code to compile and add the prototype to the class declaration with comment.
d) Finally, identify what needs to be added to the class to free dynamic memory and add the prototype to the class declaration with comment.
