Writer a program that allows the user to enter an unknown number of characters, stores those characters in a data structure (a vector) and then prints the values to the screen.
an example :
witness my exciting first use of vectors!
Enter as many letter as you like, enter ! to quit.
enter a letter: b
enter a letter: u
enter a letter: r
enter a letter: r
enter a letter: p
enter a letter: !
Great! you entered: burrp
The frist character is : b
The last character is : p
Note: the exclamation point was never stored in the vector.
Goal: recognize that vector objects allow greater flexibility that arrays and how to use a vector in a program.
you do not need to specify size when using vectors.
