对于第4个printf,首先执行++i,返回i,此时i为8,再执行i++,返回值是8,此时i为9,依次将i,8也就是9,8压入栈中,得到输出结果。 上面的分析也是基于VS搞的,不过准确来说函数多个参数的计算顺序是未定义的(the order of evaluation of function arguments are undefined)。笔试题目的运行结果随不同的编译器而异。
CGMP refers to the Current Good Manufacturing Practice regulations enforced by the FDA.

Angel investors are usually people who have made their money in another industry and are looking to invest in a high-growth startup. They're often more interested in the potential return on their investment than in the day-to-day operations of the company.Angel rounds can range from a few ...
无锁编程主要依靠原子操作(Atomic Operations)来实现。原子操作是一种不可分割的操作,保证在执行过程中不会被其他线程中断。在C++中,这通常通过 std::atomic 类型和相关函数实现,它们可以对基本数据类型进行无锁操作。 2.1.3 优势与应用场景 性能提升:由于减少了线程阻塞和上下文切换,无锁编程可以显著提高程序的性能,...
第二个保证,线程2知道线程1的执行顺序,线程1知道线程2的执行顺序。Thread 2 sees all operations of thread 1 in the source code order of thread 1。2个线程的执行有个总的“已经确定好的”执行顺序,我们把它称为“单一全序”。 而这个确定好的顺序可能是下面6种中的一种, 3...

因为它只对你的操作系统有要求,比如 Windows 上编译的动态库是 .dll 文件,Linux 上编译的动态库是 .so 文件,只要操作系统一致,那么任何提供了 ctypes 模块的 Python 解释器都可以调用。这种方式的使用场景是 Python 和 C / C++ 不需要做太多的交互,比如嵌入式设备,可能只是简单调用底层驱动提供的某个接口而已。

Any — The C function is indifferent to the layout of input array data. This would be the case if, for example, the function performs only element-wise operations on the data. Not specified — The C function makes no assumption about the layout of input array data. Compared to the Any ...
