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; };  I need help writing the definition of the member function set so the instance varialbes are set according to the parameters. I also need help in writing the definition of the member function manipulation that returns a decimal with: the value of the description as "rectangle", returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of the description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns with the value -1.

using System; class main { publicstaticvoid Main(string[] args) { int number = 1; while (number <= 88) { int i; Random r = new Random(); int[] randNo=newint[3]; for(i=0;i<3;i++) { randNo[i]= r.Next(1,88); Console.WriteLine("Random Number between 1 and 88 is "+randNo[i]); } } } }   This code is supposed to count from 1-88 and then select three random numbers from the list but instead it generates an infinite loop of random numers between 1-88. how can it be fixed?

Complete the isExact Reverse() method in Reverse.java as follows: The method takes two Strings x and y as parameters and returns a boolean. The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below. Argument String x "ba" "desserts" "apple" "regal" "war" "pal" Argument String y "stressed" "apple" "lager" "raw" "slap" Return Value false true false true true false
