In Java, string method concat is used for __________ strings.

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?

Please mention what sample run

C++ CODE HELP NEEDED NEED  MISSING CODE THAT WILL  Read an integer as the number of Goat objects. Assign myGoats with an array of that many Goat objects. For each object, call object's Read() followed by the object's Print(). Ex: If the input is 2 5 87 7 71, then the output is: Goat's age: 5 Goat's weight: 87 Goat's age: 7 Goat's weight: 71 Goat with age 7 and weight 71 is deallocated. Goat with age 5 and weight 87 is deallocated.   #include <iostream>using namespace std; class Goat {   public:      Goat();      void Read();      void Print();      ~Goat();   private:      int age;      int weight;};Goat::Goat() {   age = 0;   weight = 0;}void Goat::Read() {   cin >> age;   cin >> weight;}void Goat::Print() {   cout << "Goat's age: " << age << endl;   cout << "Goat's weight: " << weight << endl;}Goat::~Goat() { // Covered in section on Destructors.   cout << "Goat with age " << age << " and weight " <<…

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
