Description

1. Write three C++ functions which read strings from the standard input and print them in the
   reverse order. The first program should be implemented using an array, the second one using a
   vector and the third one using a stack. Argue on the best choice in the README file.

2. Write three C++ functions which read strings from the standard input and print them in the input order. The first program should be implemented using an array, the second one using a vector and the third one using a queue. Argue on the best choice in the README file.

The declaration of functions in assignment.h are:

void ex1_reverse_array();
void ex1_reverse_vector();
void ex1_reverse_stack();
void ex1_ordered_array();
void ex1_ordered_vector();
void ex1_ordered_queue();
