The training organized by the school is aimed at improving the employment rate after graduation. The training content is indeed something that I have not been exposed to in previous classes, and it is mainly embedded. This series will be used to record this training, which mainly includes the following points:
1. Basics of C language (pushing box game)
2. Data structure related (implementing a simple database)
3. File related (everything in Linux is a file, and you can also edit pictures directly. Haha, I always thought that picture related was very advanced)
4. TCP related (server and client)
5. C++ basics (object-oriented, overloading, references, namespaces, etc.)
6. Qt basics
7. Simple image transmission (direct tcp real-time transmission of images, qt end display)
8. Linux and qt connect to control the home through mqtt
The first part is to use C language to complete a push box game (linux environment) :
The first thing to understand is that the command line can use printf to output different colors , so that we can complete the production of this mini game directly on the command line. Walls, boxes, and characters are all displayed with spaces of different colors . Secondly, the keyboard we use for input is too troublesome if we have to hit Enter every time we input, so we need to use the following sentence to achieve the C language standard Input read immediately (ICANON)
system("stty -icanon");//直接获取键盘值，不用按enterEach image refresh clears the command line and displays it again.
