2. Consider the following statements: class temporary { public: void set(string, double, double); void print(); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); string getDescription() const; double getFirst()const; double getSecond()const; temporary(string = "", double = 0.0, double = 0.0); private: string description; double first; double second; }; Now answer the following questions: a. Write the definition of the member function set so that the instance variables are set according to the parameters. b. Write the definition of the member function manipulate that returns a decimal number as follows: If the value of description is "rectangle", it returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of description is "sphere", it returns the volume of the sphere with radius first; if the value of description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns the value -1. c. Write the definition of the function print to print the values of the instance variables and the values returned by the function manipulate. For example, if description = "rectangle", first = 8.5, and second = 5, it should print: rectangle: length = 8.50, width = 5.00, area = 42.50 d. Write the definition of the constructor so that it initializes the instance variables using the function set. e. Write the definition of the remaining functions to set or retrieve the values of the instance variables. Note that the function get returns the values of all instance variables.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Can you help me please:
2. Consider the following statements:
class temporary
{
public:
void set(string, double, double);
void print();
double manipulate();
void get(string&, double&, double&);
void setDescription(string);
void setFirst(double);
void setSecond(double);
string getDescription() const; double getFirst()const; double getSecond()const;
temporary(string = "", double = 0.0, double = 0.0);
private: string description; double first; double second; };
Now answer the following questions:
a. Write the definition of the member function set so that the instance variables are set according to the parameters.
b. Write the definition of the member function manipulate that returns a decimal number as follows: If the value of description is "rectangle", it returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of description is "sphere", it returns the volume of the sphere with radius first; if the value of description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns the value -1.
c. Write the definition of the function print to print the values of the instance variables and the values returned by the function manipulate. For example, if description = "rectangle", first = 8.5, and second = 5, it should print: rectangle: length = 8.50, width = 5.00, area = 42.50
d. Write the definition of the constructor so that it initializes the instance variables using the function set.
e. Write the definition of the remaining functions to set or retrieve the values of the instance variables. Note that the function get returns the values of all instance variables.
