Summary: In this programming tutorial, we will learn different ways to convert a string into a char array in C++. Method 1: Using ‘for loop’ #include <iostream> using namespace std; int main() { string str; cout << "Enter a string \n"; getline(cin,str); //Create an empty ...

std::string在MSVC编译器下,性能略胜于QByteArray。究其原因,我认为核心在于SSO和模板。QString/QByteArray的绝大部分代码都是放在cpp文件中,性能相比模板可能会有降低。然后我尝试用静态构建跑了下,QByteArray大多数testcase都略微优于std::string,但Substr(10)和find依旧是std::string更快。 出人意料的是,QStri...
