Question

c++ please

Create a my pair class

class that uses an array to store pairs of elements. The data members of the class are first and second. Use a template to allow the class to store pairs of any type so that a pair may be (int, int) or (int, double) or (int string), or any other combination you can think of. Create a member function to display the pair in the format "value, value" with a comma separating them. Also create getters and setters for the first and second data members.

Answer 1

Please find the code below::::

#include<iostream>
#include<string>
using namespace std;
template<class T, class P>
class MyPair
{
private:
   T data1;
   P data2;
public:
   MyPair(T r,P c)
   {
       data1 = r;
       data2 = c;
   }

   void setDataOne(T r){
       data1 = r;
   }

   void setDataTwo(P r){
       data2 = r;
   }

   T getDataOne(T r){
       return data1;
   }

   T getDataTwo(T r){
       return data1;
   }

   void displayPair(){
       cout<<data1<<","<<data2<<endl;
   }
};
int main()
{
   MyPair<int,string> pair(12,"hello");
   pair.displayPair();
   return 0;
}

output:
