容器上,Qt的Split/Join用的是QList,std::string用的是std::vector。 MinGW版的std::string,Split性能惨不忍睹,不知道是std::string的锅还是std::vector的锅…… 结论: Qt由于跨平台特性,QString/QByteArray性能稳定。二者性能基本相同,部分场景下因为数据量大,性能略逊。 std::string性能和实现有关,在不同编...
先说结论：std::string在一些场景下，性能不够好，所以在适当的场景可以找到合适的替换者，一个是 Face...

如果这里改成//join()则不会发生这种现象。因此主线程会等子线程执行完才退出oops}//2. 利用分离线程处理多文档文件voidopenDocAndDisplay(conststd::string& fileName){}//打开文件booldoneEditing() {returnfalse; }//判断是否结束编辑enumclassUserCommand{OpenNewDocument, SaveDocument,EditDocument};//命令...
I am trying to build a simple example using GNU 7.3.0 #include <iostream> #include <string> #include <vector> #include <absl/strings/str_join.h> int main() { std::vector<std::string> v = {"foo","bar","baz"}; std::string s = absl::StrJoin...
