#include <iostream>
#include <tuple> 
  
using namespace std; 
  
int main()
{
    tuple <char, int, float, string> t; 
  
    t = make_tuple('z', 89, 3.14, "c++"); 
    
    cout << get<0>(t) << endl;
    cout << get<1>(t) << endl;
    cout << get<2>(t) << endl;    
    cout << get<3>(t) << endl << endl;
     
    get<0>(t) = 'a'; 
    get<1>(t) = 987;     
    get<2>(t) = 1.89;  
    get<3>(t) = "cpp"; 
     
    cout << get<0>(t) << endl;
    cout << get<1>(t) << endl;
    cout << get<2>(t) << endl;    
    cout << get<3>(t) << endl;
 
    return 0;
}
