c++

Consider the following statements:

#include  #include  class Temporary { private: string description; double first; double second; public: Temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); };

1. Write the definition of the member function set() so that the instance variables are set according to the parameters.
2. Write the definition of the constructor so that it initializes the instance variables using the function set()
3. Write the definition of the member function manipulate() that returns a decimal number (double) 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 a circle with radius first
   • if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. HINT: the volume of a cylinder is simply the area of the circle at the base times the height.
   • If the value of description is "sphere" it returns the volume of the sphere with radius first.
   • Otherwise it returns -1.0;

To save you googling what the formula for the volume of a sphere is, given the radius of the sphere, it is

V=43r3{"version":"1.1","math":"V = \frac{4}{3} \pi \; r^3"}

HINT: was included for a reason for the manipulate() function.

Given these declarations

struct NameType { string first; string last; }; struct CourseType { string name; int callNum; int credits; int grade; }; struct StudentType { NameType name; double gpa; CourseType course; }; StudentType student; 

Write C++ statements to store the following information in student:

1. name: Linda Brown
2. gpa: 3.78
3. course name: Calculus
4. course call number: 23827
5. course credits: 4
6. course grade: A
