Create a header file named "Helper.h" that defines a bool function named IsBinaryString() that takes a constant string reference parameter. It should return true if the parameter represents a binary string; otherwise, it should return false. A binary string is a string to consists only of the characters 'O' and 'l'. a class named Message that contains a private int field named id. . a private string field named msg. . a public default constructor that assigns 0 to id and assigns the empty string to msg. . a public overloaded constructor that takes an int parameter and a string parameter respectively. It assigns the int parameter to id and the string parameter to msg. . a public copy constructor. . a public overloaded assignment operator. . a public empty destructor. . a public int constant method named GetId() that takes no parameters. It returns id. . a public string constant method named GetMsg() that takes no parameters. It returns msg. . a public void method named SetId() that takes an int parameter. It assigns the parameter to id. . a public void method named SetMsg() that takes a string parameter. It assigns the parameter to msg. . a public string constant method named ToString() that takes no parameters. It returns a string in the format 2: Y where x and y are the values of id and mag respectively
