Chapter 28. From C to C++

No distinction so little excites envy as that which is derived from ancestors by a long descent.

—François de Salignac de la Mothe Fénelon

C++ was built on the older language C, and there's a lot of C code still around. That's both a blessing and a curse. It's a curse because you'll probably have to deal with a lot of ancient code. On the other hand, there will always be work for you. This chapter describes some of the differences between C and C++, as well as how to migrate from one to the other.
