<<是插入符，它将后面的内容插入到count中。<<x<<表示输出x的取值，后一个<<是用来输出后面的内容的，即 ", root is "。希望你能明白我所说的

我想大部分人都会选择最后一种输出信息吧(虽然在这之前,我们都大量使用cout输出第一种),所以我们的日志应该包括时间,日志等级,运行用户,进程ID,调用函数所在文件,以及调用时所在行数。当然总会有人不想全部输出,这将在后面给出方案。 信息虽然显示丰富,但是要尽可能让代码自己获取其他信息,调用者只需要设置最主要的...
I think that the root of the problem is that this is a parent child pair of programs. The parent uses fork to create a child process, and I am trying to print from the child process code. Under Cygwin windows, adding print statements results in output to the cygwin bash shell, but fo...
In fact, the root of all of the processes that you have in your user account doesn't have a console. The architecture if Windows in this regard is different to Linux. So with Windows, you will never have a default console available at all. This is why if you want to do console outp...
