Before that, I spent two nights looking for a train of thought
1.In fact, program development is the same, each large program is composed of hundreds of modules, a large function you can not write out, then a login verification is very easy to write out.
2.You are just because you haven’t met how to achieve this function, so you don’t know how to write.
3.Never write, don’t be discouraged, search the relevant code on the Internet to see how others write it.
4.The first step in writing is to draw the flow chart. I dare say that the flowchart is out, and your code is written out 50%.
5.Put your weird ideas on your program
6.More practice and more view
