parser to evaluate expressions

1. Compiler Patterns

Traces the evolution of a high-speed EXPRESSION EVALUATOR to demonstrate the various PATTERNS you will need to "roll your own" recursive descent compiler.

Depending on the complexity of the grammar, a hand-built recursive descent compiler may actually be the best option. It can be quicker to implement than learning a compiler-compiler system, plus it avoids having to integrate the compiler-compiler's runtime into your source code base. But it also involves risks that must be carefully weighed.

6. Internal and External Linkage in C++

Ever come across the terms internal and external linkage? Ever wanted to know what the extern keyword is for and what declaring something static does in the global scope? Then this post is for you.

A translation unit refers to an implementation (.c/.cpp) file and all header (.h/.hpp) files it includes. If an object or function inside such a translation unit has internal linkage, then that specific symbol is only visible to the linker within that translation unit. If an object or function has external linkage, the linker can also see it when processing other translation units. The static keyword, when used in the global namespace, forces a symbol to have internal linkage. The extern keyword results in a symbol having external linkage.

4. E1097: unknown attribute "no_init_all" in WinNT.h in Windows SDK 10.0.18362.0

when I compiled the example on stackoverflow, I got this error message:

Error (active) E1097 unknown attribute "no_init_all"

E1097: unknown attribute "no_init_all" in WinNT.h in Windows SDK 10.0.18362.0

solution is to add the following code into stdAfx.h file:

#if (_MSC_VER >= 1915)
#define no_init_all deprecated
#endif


There is a bug in WinNT.h in the latest Windows SDK (10.0.18362.0). There is the following code in WinNT.h to disable this warning:
#if (_MSC_VER >= 1915)
#pragma warning(disable:4845) // __declspec(no_init_all) used but d1initall not set
#endif
However, in the latest Windows SDK, this is no longer warning 4845, but is instead error 1097 (E1097: unknown attribute “no_init_all”).

As a result this error now leaks out into the rest of the project.

error message: tchar is not defined

when I compiled the code "matrix library in C", I got following similar error messages. So I did research and find the solution to it.

tchar is not defined
_tchar is undefined
Error C3861 'printf': identifier not found MatrixLib c:\demo_cpp\matrixlib\matrixlib\matlib.h 16

another error is:
‘RAND_MAX’ undeclared (first use in this function)

1. Why do I receive this error when generating a random float?
2. TCHAR vs _TCHAR

TCHAR and _TCHAR are identical, although since TCHAR doesn't have a leading underscore, Microsoft aren't allowed to reserved it as a keyword (imagine if you had a variable called TCHAR. Think what would happen). Hence TCHAR will not be #defined when Language Extensions are disabled (/Za).

TCHAR is defined in winnt.h (which you'll get when you #include ), and also tchar.h under /Ze. _TCHAR is available only in tchar.h (which also #defines _TSCHAR and _TUCHAR). Those are unsigned/signed variants of the normal TCHAR data type.

You've probably already read it, but just in case, the strings section of Codeproject has useful info.

C++ standard library

C++ standard library

1. MODULE 23a - C++ NAMESPACES 2
• C++ library entities such as functions and classes are declared or/and defined in one or more standard headers. To make use of a library entity in a program, as in C program, we have to include them using the include preprocessor directive, #include.
• The Standard C++ library headers as shown in Table 23.1 together with the 16 Standard C headers (C++ wrappers - get the ideas of the wrappersswig.org) shown in Table 23.2, constitute an implementation of the C++ library.
• If you want to use functions, structure, macros and other built-in item available in the Standard C headers in C++ programming environment or ISO/IEC C++ compilers, use the C++ wrappers.
• These C++ wrappers are C headers that prefixed by c character such as from .
• Other than those ISO/IEC C and ISO/IEC C++ Standard headers should be implementation dependant, it is non standard. Keep in mind that there are a lot more non standard headers that you will find.
