Read the First Word

A text file contains words separated by spaces and newlines, for example:

hello world

Write a function string firstWord(const string& filename) that returns the first word of the file. The starter already opens the file as ifstream in and declares a string w; you only need to add the one line that reads a word from in into w with >>.

The test prints the returned word on its own line, for example (see Expected Output).

Do NOT write a main function.

Expected Output:

hello↵
apple↵

= newline. The output ends with a newline — print one after the last line.
