) Execution process:A: Calculate the value of an expression firstB: Match each case, and if there is one, execute the corresponding statement body and see the break end.C: If there is no match, execute the default statement body n+1.(4) Precautions:A:case can only be constants, cannot be variables, and values after multiple case cannot appear the sameCan B:default be omitted?It can be omitted, but it is not recommended, because it is used to prompt for incorrect conditions.Special cases:Case opt

C language learning notes (6): How to differentiate pointer arrays and array pointers from the surface of variable declarations, language learning pointers Example:Int * p [5] is a pointer ArrayInt (* p) [5] is an array pointerTo distinguish the two, you only need to look at the modifier around variable name p. Here we need to clarify two points: 1. No matter whether int * p [5] Or int (* p) [5], it should not be regarded as a whole, but as some

variables, constants, Functions * PHP built-in functions are also different, Use less time complexity. Example Isset () and array_key_exists () differences * Avoid using the PHP Magic function * Disable the @ ERROR suppressor, resulting in additional overhead * Reasonable use of memory, using unset () to release unused memory in a timely manner * Use regular Expressions sparingly * avoid doing operations within loops for ($i =0;strlen ($STR), $i + +) {} * reduce compute-intensive business (PHP

Surface was released, and I quickly purchased one. I want to study it and see if I can make some applications on it. I tried it for a few days and summarized some of my feelings.Poor experience:1. There are few applications in the Win8 RT mode PC, and none of the most common software input methods are available.2. There are few applications under a tablet. Although it is growing every day, there are still few software commonly used or evaluated on oth

3. find the maximum and the sub-arrayTitle :Enter an array of shapes with positive and negative numbers in the array.One or more consecutive integers in an array make up a sub-array, each of which has a and.The maximum of the and of all sub-arrays. Requires a time complexity of O (n). For example, the input array is 1,-2, 3, ten, -4, 7, 2,-5, and the largest subarray is 3, ten, -4, 7, 2,So the output is the and of the subarray. //starting with the first number plus, and credited as Sum, with a v

I want to create a wall on a skewed face. Is there any sample code for reference? Jeremy has a simple piece of code here. The object document is a project that contains a Conceptual Mass Family instance. The code first retrieves the faces (-1, 0, 1) in the normal direction of the conceptual block, and then creates a wall on this surface. [Csharp] void CreateFaceWall (Document doc) {FilteredElementCollector collector = new FilteredElementCollector (doc

our business logic. Razor syntax This is a newly added syntax structure in MVC 3, which we can use to complete our display of data in the view layer, but there are a lot of questions to note with the @ symbol. Can we think of it? The razor syntax itself is a very elegant grammatical structure. For exception handling, 404, 500 and other special errors of the page, log processing, performance optimization, program security considerations and so on these are we as programmers should grasp the

like this confusing Java exception interview, because it doesn't make it easy to find out whether it's IOException or exception. You can also find some confusing questions about Java errors and exceptions in the Java puzzles of Joshua Bloach and Neil Gafter.I also often see face questions about Java errors and anomalies encountered in some new and experienced Java interviewers. Of course there are a lot of questions about the exception that I did not relate to, and if you have some good questio

Getting started with JavaSE 12: static usage of Java surface objects We can create multiple objects of this Class Based on a class. Each object has its own members and is independent of each other. However, in some cases, we prefer All objects in this class share the same member. Now it's time for static to show its strength. The modified members in Java are called static members or class members. It belongs to the whole class, not to a certain object
