Scala Project - Churn Emails - Count the Number of Lines

Scala uses scala.io.Source class to read the files from the operating system. Here is one example code on how you can read each line from a file named new.txt:

import scala.io.Source;
for (line <-Source.fromFile("new.txt").getLines) {
    println(line)
}

A complete file path can also be specified instead of a standalone file name.

INSTRUCTIONS

Define a function number_of_lines
Open the file mbox-short.txt which is located at /cxldata/datasets/project/mbox-short.txt and read it to get each line using getLines function
Write the logic to count the total number of lines
Return the count of the number of lines
Call the function in the next cell

Note: If your logic is correct then your function should return 1910.
