Write a funciton in C/C++ that has the following signature:
char ** parseCommandLine(string aCommandLine)
This function takes the input parameter and splits that string up into an array of component tokens that are
returned to the caller. As this is assumed to be a Linux command line (for example, from the terminal application),
you need to be able to handle certain special cases: (1) file redirection with the < and > characters, (2) file
redirection with the <<, and (3) the pipe is the only other character used as a seperator. character |. Otherwise,
you may assume that the any white-space character is a separator.
For example, the following is a valid command in the Bash shell:
1 grep x < myfile .textbfin > myfile . out
This would be parsed into four tokens: grep,x,myfile.in and myfile.out.
Your function needs to return a pointer to a dynamically allocated array of C-strings (remembering that a
double-pointer is C++ is another way to say that statement). The seemingly odd return type is required by some
of the system call code you will use in your first assignment.
