In C Using the standard library queue and stack classes impl

In C++

Using the standard library queue and stack classes implement the following data structures stack of queues queue of deques deque of stacks Test each of these structures by pushing 5 objects of 3 integers into them and corresponding output. You do not need to define any new classes; it is simply a matter of creating containers of containers of the appropriate type (std::stack, std::queue, and std::deque) using STL containers.

Solution

#include <iostream>
#include <deque>
#include <queue>
#include <stack>
#include <string>
#include <utility>

using namespace std;

int main()
{
   std::queue<int> q1 ;

   std::queue<int> testQ =sq.top();
  
   for(int i=0;i<3;i++)
   {
   int temp=testQ.front(); //The answer should display the elements of top of stack, ie q5.
   testQ.pop();
   cout<<temp<<endl;

   int temp=testDQ.front(); //The answer should display the elements of front of queue,ie of q1.
   testDQ.pop_front();
   cout<<temp<<endl;
   }
   //-------------------------------------------------------------------------------------------
  
   deque<stack<int> > ds;
  
   std::stack<int> s1 ;
   s1.push(1);
