File input/output is part of Short Circuit's Console Program Basics selection.
Task

Create a file called   "output.txt",   and place in it the contents of the file   "input.txt",   via an intermediate variable.

In other words, your program will demonstrate:

   how to read from a file into a variable
   how to write a variable's contents into a file


Oneliners that skip the intermediate variable are of secondary interest — operating systems have copy commands for that.




src <- file("input.txt", "r")
dest <- file("output.txt", "w")
 
fc <- readLines(src, -1)
writeLines(fc, dest)
close(src); close(dest)
