Commonly used vector APIs

The following table shows some commonly used vector APIs:

It would be really fun and convenient to read and print to/from the vector using istream_iterator and ostream_iterator. The following code demonstrates the use of a vector:

#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>
using namespace std;

int main () {
    vector<int> v;

    cout << "\nType empty string to end the input once you are done feeding the vector" << endl;
    cout << "\nEnter some numbers to feed the vector ..." << endl;
   

    istream_iterator<int> start_input(cin);
    istream_iterator<int> end_input;

    copy ( start_input, end_input, back_inserter( v ) );


    cout << "\nPrint the vector ..." << endl;
    copy ( v.begin(), v.end(), ostream_iterator<int>(cout, "\t") );
    cout << endl;

 
    return 0;
