6.13: Word Count

Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a “word” to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.

Input Notes:There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read.

Output Notes (Prompts and Labels):
The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt.

The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the program.
