在C++ Primer一书中,对于运算符的优先级是这样描述的: Precedence specifies how the operands are grouped. It says nothing about the order in which the operands are evaluated. 意识是说优先级规定操作数的结合方式,但并未说明操作数的计算顺序。举个例子: 6+3*4+2 如果直接按照从左到右的计算次序得到的...
Evaluation Order 以下引用内容来自The C Programming Language - 2.12 Precedence and Order of Evaluation: C, like most languages, does not specify the order in which the operands of an operator are evaluated. (The exceptions are &&, ||, ?:, and `,'.) 因此可知,C 标准中并未指定对操作符的操...
Note that the order of evaluation problem is not solved by the use of parentheses, as this is not a precedence issue. The following notes give some guidance on how dependence on order of evaluation may occur, and therefore may assist in adopting the rule. increment or decrement operators As ...
Precedence and associativity are independent from order of evaluation. The standard itself doesn't specify precedence levels. They are derived from the grammar. In C++, the conditional operator has the same precedence as assignment operators, and prefix ++ and -- and assignment operators don't ...
The following rules are used to elect an RP from multiple C-RPs, in descending order of precedence: The C-RP with the interface address that has the longest mask wins. The C-RP with highest priority wins. The C-RP with the largest hash value wins. The C-RP with the largest address ...

If this option is set on the command line, the new command-line value takes precedence over the precompiler default, the system configuration file specification, and the user configuration file specification. Finally, an inline specification takes precedence over all preceding defaults. See the ...
If enabled, the build system will ignore Z80_WITH_CMAKE_SUPPORT and Z80_WITH_PKGCONFIG_SUPPORT, as no libraries or support files will be installed. The default is NO. -DZ80_SHARED_LIBS=(YES|NO) Build the emulator as a shared library, rather than static. This option takes precedence ...
