Question :

Write a program that takes two command line arguments which are file names. The program should read the first file line-by-line or character-by-character and write each line into the second file substituting numbers for letters according to the following substitution list.

a or A = 4

e or E = 3

i or I = 1

o or O = 0

t or T = 7

The program should include a "usage" method that displays the correct command line syntax if two file names are not provided.

Example: If my input file says Hello, World! This is Leslie , then my output file will contain H3ll0 W0rld! 7h1s 1s L3sl13.
