How can I have cd show the directory it switches into?

Question

I have made my command prompt ($PS1) to be just username.../current_directory (using the 3 dots because my directory structure has lots of levels and they were taking up too much of the command line prompt).
However this would work better if, when I cd'd into a directory, the cd command showed what directory I get changed into. How can I have this happen?

btw my command prompt setting (that I don't wish to change) to do username...current_dir is:

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u.../${PWD##*/}\$ '
fi

With zsh

chpwd() pwd

Then, the current directory is printed whenever it changes (upon cd, pushd, popd...).

With ksh, bash or zsh:

cd() {
  builtin cd "$@" && pwd
}

(you'd typically put those in your shell configuration file)
