As a result, we are wasting time by tracking code.should be replaced with constants:1 Con

I 've been away from C/C ++ for a long time. I just saw that I found that the basic skills I 've learned are not clear about # define and typedef ......

Objective C # Principle 22: Define external interfaces with events Item 22: Define outgoing interfaces with events You can use events to define some external interfaces for your type. The event is based on the delegate, because the delegate can provide type-safe function signature to the event handle. In addition, most examples of delegation are described by

Recall: # define usage, Ansi c stipulates that: # can contain spaces or tabs, and # can contain spaces between the command and other parts. It can appear anywhere and the scope ranges from the definition to the end of the file. Before preprocessing, the system deletes the combination of backslash and linefeed. Therefore, commands can be extended to several physical rows, which form a single logical row. // Each #
