Suppose we have the following declarations, which compile error-free. C1 obj1 = new C1(); C2 obj2 = new C2(); Which of the following are valid? Check all that apply. options: a) I1 x = obj1; b) I2 x = obj1; c) I1 x = obj2; d) I2 x = obj2;

You are said to store data of Hospitals in a city. For that purpose, you are asked to develop a structure of maxHeap using these structures in c++. You have to submit Hospital. h file only class Hospital { string HospitalName;string Address;string HospitalID;public:Hospital(); Hospital(string ,string ,string); Hospital(string HospitalID); // conversion Constructor string getHospitalName()const; string getHospitalId()const; string getAddress()const; void setHospitalName(string); void setHospitalId(string);void setAddress(string); // Relational operators with respect to Hospital Idbool operator<(Hospital)const;bool operator<=(Hospital)const;bool operator>(Hospital)const; bool operator>=(Hospital)const; bool operator==(Hospital)const;bool operator!=(Hospital)const; // output stream operatorfriend ostream& operator<<(ostream&, const Hospital& ref); s}; ostream& operator<<(ostream&, const Hospital& ref); class MaxHeap { public:class Node…

Correct the following code fragment and what will be the final results of the variable a and b: class A { protected int x1,y1,z; public: A(a, b,c):x1(a+2),y1 (b-1),z(c+2) { for(i=0; i<5;i++) x1++; y1++;z++;}}; class B {protected: int x,y; public: B(a,b):x(a+1),y(b+2) { for(i=0; i<5;i++) x+=2; y+=1;}}; class D:public B, virtual public A { private: int a,b; public: D(k,m,n): a(k+n), B(k,m),b(n+2),A(k,m,n) { a=a+1;b=b+1;}}; int main() {D ob(4,2,5);}

Hello, I'm working on this hangman simulation in C++. The code runs but it doesn't count wrong guesses after one letter is guessed correctly. Also, the body of the hangman comes out wrong. Could you help?         #include<iostream>#include<cstring> // for string class functions#include<fstream>#include <cctype>using namespace std; int main(){    // define variable to get the response from user "Yes" or "No"    string response;    // Define index variable    int w = 0;    // define number of words that need to be guessed by the user assume 4    const int WORDS = 4;        // loop    do    {        // we will define the hangman body        const char body[] = "o/|\\|\\";        // here we define the words        string words[WORDS] = {"MACAW", "SADDLE", "TOASTER", "XENOICIDE"};        // fetch size or length        string xword(words[w].length(),'*');        // define iterator to fetch the words        string::iterator ix = xword.begin();        string::iterator i…
