3. How GCC letters represent a functionFor the C language, the function is the core, and everything revolves around the function. For a function, some of its main features are as follows:1. There is a return value, where we do not think that the return value of the function is void;2. It has incoming parameters, and this parameter number is uncertain, can be much less, or can not;3. It has a function name, the name is unique, that is, the same project, can not have the same name as many function

Today we are talking about QString. The reason why QString is taken out separately is that string is a very common data structure, even in many languages, such as JavaScript, string is implemented as a basic data structure similar to int.
Every GUI program requires a string. These strings can be used as prompts on the interface or as common data structu

complete, put the code under AIX. Chinese Printing is garbled !!!
Analysis: Eclipse automatically compiled files into UTF-8 format. This is also true for Chinese characters. However, the current character set on the AIX server is not for the UTF-8. It may be GB2312 or GB18030.
It should be the GBXX character set that cannot be displayed on the UTF-8. The system cannot adapt to my programs, so all files must be transcoded. Unfortunately, some Ubuntu source code is obtained from windows. It is

Although there are some solutions on the internet, however, it is troublesome to obtain the original file instead of directly decrypting it. I used ollydbg to solve this problem perfectly.
After the ollydbg is opened, the encrypted execution file is opened through the file. When the password window is displaye
