虚继承之单继承的内存布局

The std::endl part of the code above is of special interest. (By the way, it's pronounced end ell; the last character is the lowercase letter L, not the number 1.). It's a manipulator; that is, an argument that affects the I/O operation is a certain way. The endl manipulator, for example, has two effects:

It forces output flushing, meaning that it causes cout to output its buffered contents immediately.

It appends a line break after the output operation.
