Question

The following defines an object for this question

class Question4 {

private:

int month, day, year;

public:

Question4 (int month =1, int day=1, int year=1){

this->month=month;

this->day=day;

this->year=year;

}

void printIt(){

cout <<month <<"/"<<day<<"/"<<year<<endl;

}

};

Question4 one(10,26,2017), two (2,15,1946), three(1,12,1997);

Give the code to create a standard template library(STL) container to hold a group these objects. you may choose your container.

Give the code to add the objects one,two and three to container you declare for first part of this question

Give a loop to step through container and output all the objects

Explanation / Answer

I would use vector stl container to hold the Question4 objects. below is the code written in main function.

#include <vector> // add this header file at the top of the file if the main function is going to be placed in the same file where Question4 class is declared

int main()
{

std::vector<Question4> q4vector(3);

    // Add the Question4 objects to the vector
    q4vector.push_back(one); // add object one to the vector
    q4vector.push_back(two); // add object two to the vector
    q4vector.push_back(three); // add object three to the vector

   // use iterator on the vector to iterate through the vector and output the objects
   vector<Question4>::iterator q4it; // declare an iterator q4it for q4vector vector
  
   // use for loop to iterate through the vector
   for ( q4it = q4vector.begin(); q4it != q4vector.end(); ++q4it ) // point the iterator to the begining of the vector                                                           // and start iterating through.
   {   
       // q4it will point to each object of the Question4 class that were placed in the vector
        q4it->printIt(); // print the data in the each object in the same order of insertion into the vector
    }
return 0;
}
