Question

USING C++

Consider class Thing t string secretName unsigned mschiefLevel:; public: ThingO ...) Thing( const Thing &t)(·.) // Assume these three // member functions const Thing &operator-(.. -ThingO are properly class CatInTheHat Thing thing_1; Thing thing 2; Thing "seuss; /points to an array of suessize Things unsigned suessize; public: There isn't enough info here to write this, so I'm not asking. CatInTheHat( const CatIn TheHat &cat); const CatInTheHat &operator-(const CatInTheHat &cat); CatInTheHat0; 5) Write the CatInTheHat copy constructor. (2 pts extra for using a member initial list. (Correctly.) atlnTheHat copy constructor. (2 pts extra for using a member initialization 6) Write the CatInTheHat assignment operator. 7) Write the CatInTheHat destructor Write the Thing destructor. 8) a) (3 pts.) Declare a vector of int's 9) b) (8 pts.) Declare a vector of vectors of int's c) (1 pt.) In b), why can't you put 2'S characters next to each other?

Answer 1

(5)CatInTheHat(const CatInTheHat & cat){
   thing_1 = cat.thing_1;
   thing_2 = cat.thing_2;
   seussize = cat.seussize;
   seuss = new Thing[seussize];
  
   for(int i=0;i<seussize;i++)seuss[i] = cat.seuss[i];
}

(6)const CatInTheHat& operator=(const CatInTheHat & cat){
   CatInTheHat newCat;
   newCat.thing_1 = cat.thing_1;
   newCat.thing_2 = cat.thing_2;
  
   newCat.seussize = cat.seussize;
   newCat.seuss = new Thing[seussize];
   for(int i=0;i<newCat.seussize;i++)newCat.seuss[i] = cat.seuss[i];
   return newCat;
}

(7)~CatInTheHat(){
   delete(seuss);
}
(8)~Thing(){
   secretName = "";
   mschiefLevel = 0;
}

(9)(a)vector<int>vec;
(b)vector< vector<int> > vec(M,N);
(c)we can not put two > character together because it will confused with (>>(input in c++ cin>>num)).
