String: a char array ending with an empty character \ 0How to define a string in a program
1. string constant (string text): refers to any character in a pair of double quotation marks. The characters in double quotation marks plus the ending sign \ 0 characters automatically provided by the compiler are stored in memory as a string. It is often used as a parameter for printf and puts.
2. String Array: when defining a string array, the compiler must know how much space it need
. Handler
Message processor. Through the handler object, we can encapsulate the message object, and then add the message object to messagequeue through sendmessage (MSG); When messagequeue loops to this message, the handlemessage () method of the handler object corresponding to the message object will be called to process it. Because the handlemessage () method processes messages, we should write a class that inherits from handler and then process the
