As we all know, using Conditional compilation allows our C code to support different platforms. However, it is obvious that a large number of pre-processing commands such as # ifdef and # endif are used in the code, because these codes are scattered

While reading a book today, I plan to try it. I will try to write the smallest program in Ubuntu. Create a hello. c file. 1 # include 2 int main (void)3 {4 printf ("Hello! \ N ");5 printf ("Hello world from process ID is % d \ n", getpid ());6

C # reflection (1) Yesterday, when I was not familiar with reflection, I thought reflection was mysterious. I went to the Internet to find the answer. Today I found a piece of code and knocked it out! Actually, reflection is that simple!Reflection

You can use the ini configuration file to read and write text, or use APIs to perform operations. The ini configuration file format is as follows:[Primary key name]Sub-key name 1 = key value 1Sub-key name 2 = key value 2Sub-key name 3 = key value 3.

If you have not read C # reflection (1), we recommend that you read C # reflection (1) first. In the previous article, some people commented on the basics of what I wrote. In fact, I also know that I am only writing the most basic syntax. The reason

Some time ago, due to frequent usage of class serialization, I have been thinking about how to use this function more conveniently. Now I will share my learning process for a while with you, if you are already familiar with class serialization,
