Your program will simulate the creation of

subdirectories (folders) on one of the disks of a

computer. The input file to your program,

prog5.dat, will contain a sequence of commands

that a user might enter from a command line, and

the output file prog5.out will contain the

operating system’s responses to these commands.

Below is an example of an input file, and on the

right is the listing of the corresponding output

file.
