vector< unsigned char> vs二进制数据的字符串
问题描述：
哪个是更好的c ++容器，用于保存和访问二进制数据？
Which is a better c++ container for holding and accessing binary data?
std::vector<unsigned char>
或
std::string
比另一个更有效吗？
$
Is one more efficient than the other?
Is one a more 'correct' usage?
答
您应该优先使用 std :: vector $ c> std :: string 。在通常情况下，两个解决方案几乎是等价的，但 std :: string s专为字符串和字符串操作设计，这不是您的预期用途。
You should prefer std::vector over std::string. In common cases both solutions can be almost equivalent, but std::strings are designed specifically for strings and string manipulation and that is not your intended use.
