As C grew in popularity, many programmers began to use it to program all tasks
because of its portability and efficiency--and because they liked it! At the time of its
creation, C was a much longed-for, dramatic improvement in programming languages.
Of course, C++ has carried on this tradition.
With the advent of C++, some thought that C as a distinct language would die
out. Such has not been the case. First, not all programs require the application of the
object-oriented programming features provided by C++. For example, applications
such as embedded systems are still typically programmed in C. Second, much of the
world still runs on C code, and those programs will continue to be enhanced and
maintained. While C's greatest legacy is as the foundation for C++, it will continue to
be a vibrant, widely used language for many years to come.
The Form of a C Program
Table 1-2 lists the 32 keywords that, combined with the formal C syntax, form the C
programming language. Of these, 27 were defined by the original version of C. These
five were added by the ANSI C committee: enum, const, signed, void, and volatile.
All are, of course, part of the C++ language.
