When compiling for C++, _ _TEMPLATES_ _ is defined as 1 This indicates that templates are supported The _ _TLS_ _ macro is always defined as 1 _ _TURBOC_ _ represents a hexadecimal value that is increased with each new release For C++ programs, _WCHAR_T and _WCHAR_T_DEFINED are defined as 1 to indicate that wchar_t is a built-in data type They are not defined for C programs For C++ Builder, _Windows is defined if your program is compiled for use under Windows The _ _WIN32_ _ macro is always defined as 1 For the most part, these built-in macros are used in fairly complex programming environments when several different versions of a program are developed or maintained

is incorrect because a keyword cannot contain a comment However, you should not generally place comments in the middle of expressions because it obscures their meaning
Borland C++ Builder: The Complete Reference
Comments may not be nested That is, one comment may not contain another comment For example, this code fragment causes a compile-time error:
/* this is an outer comment x = y/a; /* this is an inner comment - and causes an error */ */
You should include comments whenever they are needed to explain the operation of the code All but the most obvious functions should have a comment at the top that states what the function does, how it is called, and what it returns C++ fully supports C-style comments However, it also allows you to define a single-line comment Single line comments begin with a // and end at the end of the line Also, the new C99 standard for C allows //-style comments
Part II
The C++ Builder Function Library
Part Two examines the function library included with C++ Builder 10 begins with a discussion of linking, libraries, and headers s 11 through 19 describe the functions found in the library, with each chapter concentrating on a specific group

Borland C++ Builder: The Complete Reference
The functions described here are available for use by both C and C++ programs As you may know, the C++ language also defines a number of class libraries that may only be used by C++ programs Several of the class libraries are described in Part Three, when C++ is discussed

he creation of a C/C++ compiler involves two major efforts The first is the construction of the compiler itself The second is the creation of the function library Because the C++ Builder library contains so many functions, it is safe to assume that it required a substantial programming effort (Consider that even a description of these functions requires several hundred pages!) Every C or C++ program relies upon library functions to perform many of the tasks carried out by the program Because of the fundamental role that the library plays in your program, it is important to have an overview of how the library works Specifically, you need to understand the job the linker performs, how libraries differ from object files, and the role of headers These items are examined here
The Linker
The output of the compiler is a relocatable object file, and the output of the linker is an executable file The role the linker plays is twofold First, it physically combines the files specified in the link list into one program file Second, it resolves external references and memory addresses An external reference is created any time the code in one file refers to code found in another file This may be through either a function call or a reference to a global variable For example, when the two files shown here are linked together, File Two s reference to count must be resolved It is the linker that tells the code in File Two where count will be found in memory File One:
int count; void display(void); int main(void) { count = 10; display(); return 0; }
File Two:
#include <stdioh> extern int count; void display(void) {
