当然,也有许多扩展库对字符串处理提供了方便,其中比较好用的是boost中的string_algo库(已于C++17纳入了标准库,并改名为string_view),但本篇主要说C++11的regex库,其对复杂数据的处理能力非常强,比如可以用它来检测QQ号: std::regexqq_reg("[1-9]\\d{4,11}");boolret = std::regex_match(qq, qq_reg...
The std::string_view offers the benefits of std::string's interface without the cost of constructing an std::string object.

string str = “Test string”; cout << str.size() << endl; return 0; } (3).用strlen获取字符串长度 strlen同样也可以用于C++的string。但是需要用c_str()将C++ string转换为char*类型。 [cpp] view plain copy print ? #include #include using namespace std; void main() { strin...
