refreshing, yes, a small function incredibly divided into three kinds of situations. Perhaps the last element should be treated differently, see the code below1#include 2 #defineN 53 intMainvoid)4 {5 intI, arr[n] = {1,2,3,4,5};6 for(i =0; I 1; i++)7printf"%d", Arr[i]);8printf"%d\n", Arr[n-1]);9 return 0;Ten}There's really a printf missing, only two cases. Can it be unified again? Note that the spaces and line breaks are characters and can be abstracted as follows:You want to pick a

Java is becoming more and more widely used, and more and more people are learning java. People who have studied programming know that using basic for programming can use development tools such as QBasic, Visual Basic, and programming in C, and you can use Turbo C, Visual C +

The last time I talked about "lack of basic object-oriented skills", I would like to talk about programming habits today. Most of the bad habits we talk about today are cross-language (for beginners of C ++ and Python), and most of them require constant efforts to get rid of them. ★Random name Some new handwritten programs, when you need to define a variable name (or function name, class name, package nam

After all, it teaches Java. I didn't say anything in the first class, so I didn't tell you anything. Here's my thoughts and insights on previous programmingI am a Guilin University of Science and Technology College of Information

I am often asked how a person with little or no programming experience can begin to make a game. Until now, I have always tried my best to answer one. However, the number of problems has grown to a difficult level, so I decided to summarize all the suggestions in an article as a reference for the people. This article is intended for people who want to develop their own games, but have little or no programming
