Given the fact that Python does have a weaker UI than WinForm. So I want to combine the WinForm of C # and the bottom development of Python (Windows platform).Try to make an RSS reader. Here: http://download.csdn.net/detail/lion_awake/8240713.Mainly

13.2 Analysis of hash tables and STL maps. Compare hash tables and STL maps. How is a hash table implemented? If the input data size is small, we can use what data structure instead of hash table.AnswerCompare hash tables and STL mapsIn a hash table,

13.3 How does a virtual function in C + + work?AnswerVirtual functions rely on virtual function tables to work. If a function is modified by the keyword virtual in a class, a virtual function table is built to hold the address of the virtual

reviewed the preprocessing and variable types todayThe preprocessing is divided into three kinds: macro definition, conditional compilation, file contains three kinds of combination in the header file, you can prevent the content in the header file

There's a strange C-language problem:Char t=0; Char i=0; for (i=0; i 1); i++) { printf ("i=%u\n", i); if - ) break; }This loop does not execute once, but if you change the char in the code to int, it loops many times.Because

Learn about the display of the form, and then summarize the form's method of passing the value:1. Through the characteristics of the constructor: The value is one-way (can not pass the value of each other), the implementation of a simple code is as

Enumeration, typically used to customize some static variables, with keys and values.such as Audit status:public enum enumstate{Pending review = 1, technology audited = 2, financial audited = 3, Mister Audited =4}This allows you to use enumerations

19. Pre-processing instructions1. The # include statements in the file can only be other preprocessing directives or annotations2. #include指令中的头文件名字里不能出现非标准字符3. #include预处理指令应该跟随 or "filename" sequence4, C macros can only be extended to parentheses
