How to change the ACLs from c++?

Can anyone help me to do the following from c++ without any confirmations:

cacls c:\\personal\\file.txt /d everyone

If you don't want to mess around with the API (i.e. SetNamedSecurityInfo), you might be able to bypass the prompt like so:

echo y|cacls filename /d everyone

Since echo is a builtin, to call that command line from your program, you'd probably have to run:

cmd.exe /c echo y|cacls filename /d everyone
