Answer to Question #25513 in C++ for XieaRf

Question

design a class named MyInteger the class contains...
an int data field named value that stores the int value represented by this object
a constructor that creates a MyInteger object for the specified int value
a get method that returns the int value
the methods isEven(), isOdd(), and isPrime() that return true if the value of the object is even, odd or prime, respectively.
The static methods isEven(int), isOdd(int), and isPrime(int) that return true if the specified value is even, odd, or prime, respectively.
The static method isEven(MyInteger), isOdd(MyInteger), and isPrime(MyInteger) that return true if the specified value is even, odd, or prime, respectively.
The methods equals(int) and equals(MyInteger) that return true if the value in this object is equal to the specified value.
A static method parseInt(char[]) that converts an array of numeric characters to an int value.
A static method parseInt(String) that converts a string into an int value.
