context, {} stands for the collection, [] represents the list, the collection is not sequential, and the list is ordered. So more and more modern languages use [] to represent the list. Supplementary @yetone Answer: PHP之前很多年数组的表示形式一直是 array()，而 [ ] 方式是在PHP5.4中才引入的。如果你写过一段时间PHP，你就会发现用 [ ] 表示数组也是你内心真正想的一件事，这是顺其自然的。 And there's an array () It's too much to write, okay? PHP的数组根本就不是传统的C数组，而是 map、链表、堆、栈...... You can use the short array defin

Some time ago, in my blog on cnblogs, I talked about: References/pointers in java are not similar to references/pointers in c ++/C. Java reference, equivalent to c ++ pointer (fun3 ). Java references can be assigned null values, while c ++ references (see fun2) cannot be assigned null values. c ++ pointers can be assigned null values (fun3 ).In Java, there is no syntax for c ++ reference (fun2. The results raised unnecessary questions. I write a blog to compare and reference the pointers and re

{}. The symbolic image also meets the visual requirements. It's strange to use braces. In the mathematical context, {} represents a set, [] represents a list, and the set is ordered without order. Therefore, more and more modern languages use [] to represent the list. Add @ yetone: The array representation of PHP has been array () for many years, and the [] method was introduced in PHP5.4. If you have been writing PHP for a while, you will find

The so-called Big Talk is a spoof, the description of the various programming languages in this article, you can not all believe, nor new. The author has added a lot of personal emotion and social popular elements in describing historical facts, and the map is basically reliable. This may be fun and entertaining. The text on the piece is from this article.

, high-level language:More close to human expressionCombining a number of related instructions into one instruction, shielding the hardware operation, so that we can focus on the business logicSo1. High development efficiency2. Easy to understand3. Reduce the programmer's workload4. Reduced demand for computer knowledgeBut due to the need to translate the binary machine instructionsSo1. Slower execution speed than the underlying language2. You can use less instruction than the underlying languag

statements. python language is very clean, elegantly designed and features excellent modularity. It provides object-oriented capabilities, but does not force the user to object-oriented design. Its type system provides powerful expressive power, similar to Perl, with anonymous lambda expressions, which makes Lisp hackers feel kindly Python relies on TK to provide a convenient GUI interface development capability. python cannot be compared with C + +, but in today's high-speed CPUs, the ratio
