This program will store a roster of most popular videos with kittens. The roster can include at most 10 kittens. You will implement structures to handle kitten information. You will also use functions to manipulate the structure. (1) Create a structure kitten. The structure should contain the following attributes: name; string color; string score; integer Important! The name of the structure and each of its field must match exactly for the program to work and be graded correctly. (2) Create a struct roster. This struct should contain the following attributes: kittens: an array of struct kitten, with size 10 size; int. This variable will be updated based on the current number of kittens in the roster. In main(), create a roster called kittenRoster. This will store your kitten roster. (3) Implement function printMenu(). This function prints out a menu of options for the user to modify the roster. Each option is represented by a single character. Ex:

#include<iostream>

#include<string>

#include <fstream>

using namespace std;

struct kitten

{

  string name,color;

  int score;

};

struct roster

{

  struct kitten kittens[10];

}
