类模板basic_string存储和处理字符式对象的序列,这种对象是满足平凡类型(TrivialType)和标准布局类型(StandardLayoutType)的非数组对象。该类既不依赖字符类型,也不依赖该类型上的原生操作。操作的定义通过Traits模板形参(std::char_traits的特化或兼容的特征类)提供。
将数值转换为std::string。 令buf为一个足够容纳结果的内部转换函数缓冲区。 1)把有符号十进制整数转换为字符串,如同std::sprintf(buf,"%d", value)。 2)把有符号十进制整数转换为字符串,如同std::sprintf(buf,"%ld", value)。 3)把有符号十进制整数转换为字符串,如同std::sprintf(buf,"%lld", value)...

Original: The class template basic_stringstream implements input/output operations on memory (std::basic_string) based streams. It essentially wraps a raw string device implementation (basic_stringbuf) into a higher-level interface (basic_iostream). The complete interface to unique basic_stringbuf me...
