Today's learning is more difficult than a few days ago. We should not only understand the composition and structure of various statements, but also have the ability of logic programming. Because it is a little basic, it is not difficult to learn. Today, we also use circular statements to learn: factorial algorithm, digital factorial addition an ...

Note: all the data used in my test are of the type that can be compared in size without duplicate elements, and the sorting is in ascending order. In fact, the idea of fast sorting is very similar to bubble sorting. Bubble sorting is to complete the sorting through the continuous exchange between two adjacent elements. I think fast sorting ...

1.memcpy() 1.1 INTRODUCTION Header file: #include < string h> memcpy() is used to copy memory data. Its prototype is:     void * memcpy ( void * dest, const void * src, size_t num ); memcpy() will copy the first num bytes of the memory content indicated by src to the memory address indicated by dest. Because the passed parameters are re ...

After I first knew the pointer, I started the advanced pointer. In this part of the advanced pointer, I came into contact with a lot of knowledge about pointer. Pointer is really the essence of C language 1, Character pointer Among the types of pointers, it has been known that there is a pointer type called character pointer char* General u ...

NRF52810 transmission speed test Recently, there was a project to use the NRF52810 Bluetooth IC, so I bought a board to test. The current demand of the project is not very high, and the transmission speed can reach 1KB/S. The test results of everyone on the Internet are very good. It can be tested to 80KB/S in 1M mode, so I also want to try an ...
