CString::Mid() 是否有等价的 std::string?

Is there a std::string equivalent for CString::Mid()?

std::string 中是否有与 CString::mid() 等效的函数?

等同于 std::string::substr 具有以下界面:

basic_string substr( size_type pos = 0, size_type count = npos ) const;
constexpr basic_string substr( size_type pos = 0, size_type count = npos ) const;

您可以像这样使用它:

std::string str = "0123456789abcdefghij";

// returns [pos, size())
std::string sub1 = str.substr(10);
std::cout << sub1 << '\n';

// returns [pos, pos+count)
std::string sub2 = str.substr(5, 3);
