how to remove c compiler

For security I have read that c compilers should be removed.

If I am running Debian what is the best way to remove the c compiler with the intention that I might need to install it in the future for a kernel recompile, (the c compiler is necessary for kernel compiels correct?)

should I also uninstall libncurses5-dev?
