This post will discuss how to use std::pair as a key to std::map in C++. The std::pair in C++ binds together a pair of values of the same or different types, which can then be accessed through its first and second public members. 1. Using default order We know that the third ...
typedef int32_t data_size_t; 用C++解析输入file可以借鉴已有code:在application/predictor.hpp中。注意比较重要的是TextReader<data_size_t>predict_data_reader(data_filename, header)使用了utils下面的utils/text_reader.h 真正的predict函数在application/predictor.cpp里: /*! brief predicting on data, then ...
when dwt detect the memory r/w you set, system will trigger debug monitor excetption then we can get memorydump UART log to analysis. usage sop: 1)add the 2 source file(hal_dwt.c,hal_dwt.h)into project to compile, file at FAQ tail. 2)add the following code in the file end :<...

The second argument is of type -thrd_start_t, which is justtypedeffor a function pointer prototype. The third parameter specifies an argument that can be passed to the function. The return status codes ofthrd_createare defined using theenumvalues:thrd_success,thrd_nomemandthrd_error. ...

We can define a struct calledCompanyto encapsulate this information and then use a C-style array declaration to create an array of structs. #include<iostream>#include<string>structCompany{std::string name;std::string ceo;floatincome;intemployees;};intmain(){constintarraySize=2;Company comp_arr...
