Creating a List & Accessing its Two Ends

There are three constructors for the class list:

• list();

Create an empty list.  This is the default constructor.
• list(int n, const T& value = T());

Create a list with n elements, each having a specified value. T() is a default value.
• list(T *first, T *last);

Initialize the list, using the address range [first, last).

• T& back();

Return the value of the item at the back of the list.
• bool empty() const;

Return true if the list is empty, false otherwise.
• T& front();

Return the value of the item at the front of the list.
• void push_back(const T& value);

Add a value at the back of the list.
• void pop_back();

Remove the item at the back of the list.
• void push_front(const T& value);

Add a value at the front of the list
• void pop_front();

Remove the item at the front of the list.
• int size() const;

Return the number of elements in the list.

using namespace std;

void main()
{
 list<int> Scores;      //Call the constructor list();

 Scores.push_front(5);
 Scores.push_front(10);
 cout<<Scores.front()<<endl;
 cout<<Scores.back()<<endl;
 Scores.push_back(15);
 cout<<Scores.front()<<endl;
 cout<<Scores.back()<<endl;
}

using namespace std;

void main()
{
 list<string> Names;
 string Temp;

 for(int i=0; i<4; i++)
 {
     cout<<"Enter a name: ";
     cin>>Temp;
     Names.push_back(Temp);
     cout<<Names.front()<<endl;
     cout<<Names.back()<<endl;
 }
}

using namespace std;

 {
     cout<<"The "<<i+1<<"th front and back:"<<endl;
     cout<<Names.front()<<endl;
     cout<<Names.back()<<endl;
     Names.pop_front();
 }
}
