C++primer Supplements (First chapter: Start)

This series will summarize the interesting and easily forgotten points of C++primer in the book that is being read.

1. When the return statement includes a value, the type of the secondary return value must be the same as the function return type.

2. Operator Endl. The effect of writing this symbol is: 1. Ends the current line (carriage return). 2. Swipe the contents of the buffer associated with the device to the device.

3. Note Specifiers (/**/) cannot be nested.

4. The IStream object encountered a file terminator when the state becomes invalid (0,false). Windows has a file terminator of Crtl +z;linux for Crtl+d.

5. Include a header file that is not part of the standard library, surrounded by double quotation marks.
