Since December 15, my spare time has been tossing the PIC32MZ EC Starter Kit purchased at the end of 15. and successively wrote more than 10 essays documenting the course of my toss. Recently completed by the C language to achieve the PIC32 UART

Today's work encounters a string that is either a double character string and a flag that has several int types in the decimal point of the numeric stringFor example: "23.123"---"23123" + 3 is relatively simple. is to put the code here, later used,

Error handling is a problem that needs to be solved in any language, and there is a mechanism for handling errors only if 100% is not guaranteed to operate correctly. Exception handling is one of the error handling methods.1 Process activity record (

From (Baidu knows) to be retained from watchingFor basic mastery, the two are relatively similar. Because they are object-oriented languages, most of the syntax is similar. However, Java is relatively easy to use because Java does not have a pointer

= instanceof (Java-specific)Explain that when you get a reference to an object (such as a parameter), you may need to judge the class that the reference really points to. So you need to start at the bottom of the tree and use the instanceof operator
