Read the First Line

Write a function string firstLine(const string& filename) that returns the entire first line of the file, spaces included. For a file whose first line is to do list, it returns to do list, not just to.

The starter opens the file and declares string line; add the one call to getline that fills it.

The test prints the returned line, as shown in Expected Output.

Do NOT write a main function.

Expected Output:

to do list↵
single↵

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