using System; class Program { publicstaticvoid Main(string[] args) { int number = 1; while (number <= 88) { Console.WriteLine(number); number = number + 2; } int[] randNo = newint[88]; Random r = new Random(); int i=0; while (number <= 88) { randNo[i] = number; number+=1; i+=1; } for (i = 0; i < 3; i++) { Console.WriteLine("Random Numbers between 1 and 88 are " + randNo[r.Next(1, 88)]); } } } this code counts from 1-88 in odds and then selects three different random numbers. it keeps choosing 0 as a random number everytime. how can that be fixed?
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?
