在对单处机进行编程的过程中，对位的操作是经常遇到的。C51对位的操控能力是非常强大的。从这一点上，就可以看出C不光具有高级语言的灵活性，又有低级语言贴近硬件的特点。这也是在各个领域中都可以看到C的重要原因。在这一节中将详细讲解C51中的位操作及其应用。-In one office machine programming process, the bit operation is frequently encountered. C51 on the bit manipulation capabilities are very powerful. From that point on, you can see C not only have the flexibility of high-level language, there are low-level language closer to hardware features. This is also in various fields can be seen in C major reason. This section will explain in detail in C51 in the bit operation and its application.
