In terms of concept. Essentially, a pointer is a variable that stores the variable address. It is logically independent and can be changed, this includes changes to the address it points to and the data stored in the address it points. Reference is

When you comment out a large piece of code, it is better to use "# If 0" than to use, because the comments with "/**/" larger segments should prevent nested "/**/" in the commented-out code "/**/", this will cause the commented-out code area to be

Many people who have learned C must remember the type conversion in C, for example: Float floatnum = 1.234;Int intnum = (INT) floatnum;// Intnum = 1 This is a normal type conversion. A slightly risky conversion is as follows: Float floatnum = 1.234;

Long time ago I promised to show LINQ in a demo, Instead of just showing slides. Finally it's online so to show you how much easier it is to write code in C #3.0 than it was in C #2.0, I 've created A small webcast(About 25 minutes ). In the
