28.7 Summary
What you must do to get C to compile with a C++ compiler:
Change K&R-style function headers into standard C++ headers. Add prototypes. Rename any functions or variables that are C++ keywords. Change setjmp/longjmp calls
into catch/throw operations.
Once you've done these tasks, you have a C+1/2 program. It works, but it's really a C program in C++'s clothing. To convert it to a real C++ program, you also need to do the following:
Change malloc to new.
Change free to delete or delete
[] calls.
Turn printf and scanf calls
into cout and cin.
When turning struct declarations
into class variables, be careful of
read, write, and
memset functions that use the entire structure or
class.
