// Bad: sum should define its array as const.intsum(int*xs,intn);// Because otherwise, this will be a compilation warning:intconstxs[]={1,2,3};returnsum(xs,sizeofxs);// => warning: passing argument 2 of ‘sum’ discards ‘const’// qualifier from pointer target type Thus, using...
俄罗斯OOO Program Verification Systems公司用自己的静态源码分析产品PVS-Studio对一些知名的C/C++开源项目,诸如Apache Http Server、Chromium、Clang、CMake、MySQL等的源码进行了分析,找出了100个典型的Bugs。个人觉得这份列表对C/C++ 程序员有一定参考意义。与其说事后用静态工具分析,倒不如在编码时就提高自知自觉,避免...

最后,为了不让The Elements of Programming Style[8]未来的版本把这段代码作为不良风格的实例,我最好解释一下其中的一些代码。我使用了下面这条语句: #define TOTAL_ELEMENTS (sizeof(array) / sizeof(array[0])) 而不是: #define TOTAL_ELEMENTS (sizeof(array) / sizeof(int)) 因为前者可以在不修改#defi...
The rest of the elements of the array reference are used as arguments to the filter. For example, consider a filters parameter like this: use Inline C => DATA => filters => [ [ Ragel => '-G2' ] ]; In order for Inline::C to process this filter, it will attempt to require the...
This change may expose pointer truncation bugs in existing code. By default, this switch is on. To disable this behavior, specify /HIGHENTROPYVA:NO. The managed compiler (Visual Basic/C#) also supports /HIGHENTROPYVA for managed builds. However, in this case, the /HIGHENTROPYVAswitch is ...

the library will call the _invalid_parameter_handler and abort the process rather than allow a buffer overrun. This sample uses _countof to determine the size of the buffer. The _countof function is a new addition to the CRT that gets an array element count and, in C++ code only, uses ...

When it is sometimes ignored, it's probably bad style (typically, not testing for error conditions). If you need not check the return values of string functions like strcat(), strcpy(), and sprintf(), or output functions like printf() and putchar(), cast the offending calls to void. ...
