Putting It Together
Let’s try to tie together what you have learned in the previous section. I’ll take the MAILLIST
program from Day 2, “Wading In Deeper,” and modify it so that it uses dynamic memory
allocation. This will require a few changes. First, take a look at the modified program, and
then I’ll explain the changes. Listing 3.1 contains the modified MAILLIST program.
Listing 3.1. POINTER.CPP.
