Use std::pair to Return Two Values From the Function in C++ While functions typically return a single value, there are scenarios in which you may need to return multiple values to the caller. In such cases, a convenient approach is to employ the std::pair structure or other data structures...
How do I modify a native KV pair in ArkTS and pass the new value to the native side? How Do I obtain an object and its member variables from ArkTS on the native side? How do I correctly set the header file path in the CMakeLists.txt file? How do I import the header file...

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.

编译C++文件:g++ -g -Wall -std=c++11 test.cpp -l_lightgbm注意,用到了l_lightgbm,这个.so库是上面make install直接放入到了/usr/local/lib下。如果找不到该库,需要whereis查看一下,把相应目录加入到lib path里如:export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib ...

Not having a new-line char at the end of file breaks .h files with the Sun WorkShop compiler and it breaks .cpp files on HP. Don't put extra top-level semi-colons in code Non-portable example: int A::foo() { }; This is another problem that seems to show up more on C++ than...
