是否有 C++ 标准模板库类提供高效的字符串连接功能，类似于 C# 的 StringBuilder 或 Java 的 字符串缓冲区?
Is there a C++ Standard Template Library class that provides efficient string concatenation functionality, similar to C#'s StringBuilder or Java's StringBuffer?
推荐答案
C++ 的方式是使用 std::stringstream 或只是简单的字符串连接.C++ 字符串是可变的，因此连接的性能考虑不太重要.
The C++ way would be to use std::stringstream or just plain string concatenations. C++ strings are mutable so the performance considerations of concatenation are less of a concern.
with regards to formatting, you can do all the same formatting on a stream, but in a different way, similar to cout. or you can use a strongly typed functor which encapsulates this and provides a String.Format like interface e.g. boost::format
