//  Created by pezy on 12/15/14.
//
//  Write a program to read a sequence of strings and ints,
//  storing each into a pair. Store the pairs in a vector.
//
//  There are at least three ways to create the pairs in the program for the previous exercise.
//  Write three versions of that program, creating the pairs in each way.
//  Explain which form you think is easiest to write and understand, and why.
