;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.
