THE
FOUNDATION
OF
C++
operations, high-level mathematical computations, or string handling. As a result,
most programs include calls to various functions contained in C's standard library.
The C language defines a standard library that provides functions that perform
most commonly needed tasks. (This library is also supported by C++.) When you call a
function that is not part of the program you wrote, the compiler "remembers" its name.
Later the linker combines the code you wrote with the object code already found in the
standard library. This process is called linking.
The functions that are kept in the library are in relocatable format. This means that
the memory addresses for the various machine-code instructions have not been
absolutely defined; only offset information has been kept. When your program links
with the functions in the standard library, these memory offsets are used to create the
actual addresses used. There are several technical manuals and books that explain this
process in more detail. However, you do not need any further explanation of the actual
relocation process to program in C or use C++ Builder.
Separate Compilation
Most short C programs are completely contained within one source file. However, as a
program gets longer, so does its compile time, and long compile times make for short
The keywords defined by C subset of C++
auto
double
int
struct
break

typedef
char
extern

These additional keywords added by Borland are allowed in a C program:
