Atomic element size 16-bit increasing addresses→ ... 0C0Dh 0A0Bh ... The least significant 16-bit unit stores the value 0C0Dh, immediately followed by 0A0Bh. Note that 0C0Dh and 0A0Bh represent integers, not bit layouts (see bit numbering). 很显然“小端”机器符合“高高低低”...
类似于std::atomic, 但是任何小于8个byte的POD类都可以变成atomic的。实现的方法如下: 用一个unconstrained union 来存数据:1 2 3 4 union { Atom<Raw> data; T typedData; };T是你的类,Atom 就是std::atomic,Raw是这么来的1 typename Raw = typename detail::AtomicStructIntPick<sizeof(T)>::type...
printf("Enter two integers: ");sum=add(num1,num2); 语句和表达式 语句是 C 程序的基本执行单元,通常是函数调用、赋值、控制语句(如if、for等)或表达式。表达式是由变量、操作符和常量组成的代码片段。 示例: printf("Enter two integers: ");sum=add(num1,num2); ...
