Chapter 17, Problem 59RQE

Program Plan Intro

Vector:

• A vector is a sequence container which performs like an extensible array.
• The size of the vector is dynamic.
• The series of elements are stored in the same variable name.
• If an element is added or removed, it adjusts its size automatically which accommodates the number of elements contained in the vector.

Iterator:

• It is an object that can be used to iterate over the elements in a collection.
• It behaves like pointers that can access the information in a container.
• The content of the vector can be manipulated or printed using an Iterator.

Categories of Iterator:

• Forward
• Bi-directional
• Random access
• Input
• Output

Defining an Iterator:

Container_Type::iterator iterator_Name;

Print elements of vector using “for” loop that uses iterator:

The statement to print vector elements using “for” loop that uses iterator is given below:

vector<int>:: iterator it;

for(auto it = vect.begin(); it!= vect.end(); it++)
