“cout” cout“ - 输出代表什么？ [英] "cout << cout" - what does the output stand for?

问题描述

经过一天的编码后，我偶然写了

After a long day of coding i accidentaly wrote

cout << "some text" << cout;

而不是

cout << "some text" << endl;

现在打印出一个内存地址。它指向什么？

Now it printed out a memory address. What does it point to ?

推荐答案

std :: cout 是 std :: ostream ，在C ++ 11之前，有一个转换运算符到 void * 。看来你的代码触发了转换，给你 std :: cout 对象的地址。

std::cout is an instance of std::ostream, and, before C++11, that had a conversion operator to void*. It seems your code is triggering that conversion, giving you the address of the std::cout object.
