C++ UNIX SYSTEM CALL

I have a problem with a Unix System call in cpp, I need help correcting this issue. We are using the VI editor.

2. Move into the directory playarea. You are going to create file 'foxes' here.

my code:

system("echo 'Move into the directory play area: '; cd playarea"); system("echo 'List the files in the playarea directory: '; ls"); system("echo 'The only winning move is not to play.' > foxes"); system("echo 'The only winning move is not to play.'; vi foxes << EndOfCommands i THE QUICK BROWN FOX has 3 brother foxes and 4 sister foxes. BUT she is the slowest of all. ^[ ZZ EndOfCommands");

a) List the files in the playarea directory.

b) Remove files 'foxes' and 'wolves' from the directory.

c) Create the file foxes by input redirection, so that it will contain the following lines:

THE QUICK BROWN FOX has 3 brother foxes and 4 sister foxes. BUT she is the slowest of all.
