Total Size of All Files in The Current Directory Program Project

Write a program to calculate the total size of all files in the current directory / folder
and all sub
-folder
s. 3 different languages. Use C, C++, and Java. Upload a zip with all 3 files. After that answer the following question:

1. Was one language easier or faster to write the code for this? If so, describe in detail why, as in what about the language made that the case.

2. Even though a language may not (e.g. FORTRAN) does not support recursion, describe how you could write a program to produce the same results without using recursion. Would that approach have any limitations and if so, what would they be?
