Question

Problem 1

Define a base class named Pet. It has members (choose good data types for these)
1. Name
2. Gender (ie male/female)
3. Age
4. Weight

Add constructors, destructors, get/set methods, atleast one of each.
Define a function getDetail() that returns a int with value 0.

Define a Cat derived from Pet. This class has two private members
1. Breed
2. Type of Cat (three known types ie domestic, wild, toy)

Write constructor, destructor, get/set methods.
Override (ie re-define) getDetail() that returns the age of the Cat.

Problem 2

1. Write a program to print the values of diagonal elements of a
8x8 square matrix. Diagonal matrix is set as 8 x 8 (ie 8 rows 8 columns)
(so you can hard code the dimension)

Diagonal elements of a matrix are at index pairs (as I define) are 0,0 1,1 2,2 3,3 etc. up and
including the last indexed element.

Explanation / Answer

A1)

#include <iostream>
#include <string>

using namespace std;

class pet{
private:
   string name;
   string gender;
   int age;
   int weight;
public:
   pet();
   ~pet();
   void setname();
   void setgender();
   string getname();
   string getgender();
   void setage();
   int getage();
   void setweight();
   int getweight();
   int getdetails();
};

pet::pet(){
   setname();
   setgender();
   setage();
   setweight();
}

pet::~pet(){
   // delete object
}

void pet::setname(){
   cout << "Enter name: ";
   cin >> name;
}

void pet::setgender(){
   cout << "Enter Gender: ";
   cin >> gender;
}

void pet::setage(){
   cout << "Enter age: ";
   cin >> age;
}

void pet::setweight(){
   cout << "Enter weight: ";
   cin >> weight;
}

string pet::getname(){
   return name;
}

string pet::getgender(){
   return gender;
}

int pet::getweight(){
   return weight;
}

int pet::getage(){
   return age;
}

int pet::getdetails(){
   return 0;
}

class cat :public pet{
private:  
   string breed;
   string type;
public:
   cat();
   ~cat();
   int getdetails();
};

cat::cat(){

}

cat::~cat(){
   // delete cat object
}

int cat::getdetails(){
   pet::getdetails();
   return getage();
}

int main(){
   cout << "Enter details of pet" << endl;
   pet p = pet();
   cout << "Enter details of cat" << endl;
   cat c = cat();
   cout << "getdetails of pet returns " << p.getdetails() << endl;
   cout << "getdetails of cat returns " << c.getdetails() << endl;
   return 0;
}

A2)

#include <iostream>
#include <string>
#include <random>

using namespace std;

int main(){
   int cols = 8;
   int rows = 8;
   int **arr = new int*[rows];
   cout << "Matrix is: " << endl;
   for (int i = 0; i < rows; ++i){
       int *temp = new int[cols];
       for (int j = 0; j < cols; ++j){
           temp[j] = rand() % 10;
           cout << temp[j] << " ";
       }
       arr[i] = temp;
       cout << endl;
   }
   cout << endl;
   cout << "Diagonal elements are: ";
   for (int i = 0; i < rows; ++i){
       for (int j = 0; j < cols; ++j){
           if (i == j){
               cout << arr[i][j] << ", ";
           }
       }
   }
   cout << endl;
   return 0;
}
