A few days ago a friend asked me about the C language compiler principle and compiling process, at that time I did not explain white, today deliberately in the book and online access to information, a simple summary of the C language of the compiler

PCM data recorded with a microphone, 16bit, 48KHz, mono, and I would like to get the 16KHz sampling rate of the PCM data, then by reducing the sampling rate of the method to achieve 48000HZ to 16000HZ sample rate conversion. The conversion principle

The Memset function sets the contents of each byte in a piece of memory pointed to by S to the ASCII value specified by CH, and the size of the block is specified by the third parameter, which is typically initialized for the newly requested memory,

The list container corresponds to a list of common data structures. The list container supports fast random inserts, deletes, but does not support fast random access elements; This is not the same as the vector container, vector containers do not

Chapter 17th Tools for large-scale programs 1 Large-scale applications often have the following special requirements: More stringent uptime and more robust error detection and error handling.        Error handling often has to be done across

Decltype Introduction We used the typeid operator to query the type of a variable, which is performed at run time. The RTTI mechanism produces a type_info type of data for each type, and the typeID query returns a variable that type_info the data
