Vectors
A vector is a container similar to an array, but has no fixed size and can dynamically grow by pushing elements to it. A reference to all of its member functions can be found here: http://www.cplusplus.com/reference/vector/vector/
Ex Code
#include <iostream>
#include <vector>
#include <iterator>
#include <string>
using namespace std;
void vector_ex() {
vector<string> students;
cout << "\nVECTOR ITERATORS\n";
students.push_back("Mary");
students.push_back("Dave");
students.push_back("Sara");
students.push_back("Bill");
cout << "\nWithout iterator\n";
for (int i = 0; i < students.size(); i++) {
cout << students[i] << endl;
}
cout << "\nWith iterator\n";
vector<string>::iterator itr;
for (itr = students.begin(); itr != students.end(); ++itr) {
cout << *itr << endl;
}
cout << endl;
}
int main() {
vector_ex();
return 0;
}Output
Without iterator
Mary
Dave
Sara
Bill
With iterator

Dave
Sara
