to_string example to_string函数实现 (2)字符串流stringstream 标准库定义了三种类型字符串流:istringstream、ostringstream以及stringstream,看名字就知道这几种类型和iostream中的几个非常类似,分别可以读、写以及读和写string类型,它们也确实是从iostream类型派生而来的。要使用它们需要包含sstream头文件。 除了从iostream继...

我知道sprintf等的'_s'版本更安全,并且上面的代码也可以重构为使用std :: stringstream等。但这是旧代码。 我同意上述代码实际上至少应该使用%d或重构为使用类似std :: stringstream的东西。 出于好奇,上面的代码会产生不正确的结果吗?由于此遗留代码已经存在了相当长的一段时间,并且看起来运行良好。
