命令式编程(Imperative Programming)和声明式编程(Declarative Programming)都是计算机编程的范式,它们有着不同的特点和适用场景。 首先,我们讨论命令式编程。在命令式编程中,程序员需要明确地告诉计算机需要执行哪些步骤来达到预期的结果。我们可以把这种范式比作烹饪食谱:食谱会明确地告诉你需要什么成分,然后应该按照什么顺序...
命令式编程（Imperative Programming）和声明式编程（Declarative Programming）是计算机编程的两种范式，各自有独特特点及适用场景。命令式编程侧重于详细说明计算机执行步骤以达到结果。类比烹饪，编程者需明确告知需要哪些材料及操作顺序。例如，计算数组元素总和，Python命令式编程代码如下：我们直接告知计算机执行过...

The idea of imperative programming goes way back to 1950s, which is when the first high-level programming languages have been created. With 72 vacuum tube transistors and 18K of memory at disposal, the programs must have been as performant as possible. The only way to achieve it was to wri...
while declarative programming abstracts away the details, focusing on what the final outcome should be. Both paradigms have their strengths, with imperative programming being more suitable for tasks where precise control is needed, and declarative programming offering simplicity and expressiveness for tasks...
1Computer/database/programming language/etc Examples of imperative and declarative codeLink to this section Taking a simple example, let’s say we wish to double all the numbers in an array. We could do this in an imperative style like so: ...
Declarative and imperative are two different programming paradigms. Many articles canbe found on the internetabout these paradigms. In summary, a declarative program describes the desired end result whereas an imperative program describes the exact steps to achieve the result. Both paradigms have pros ...
Effective C# Item 24: Prefer Declarative to Imperative Programming 声明式编程是一种简洁的程序行为描述方式。声明式编程让我们可以通过使用声明来达到定义程序行为的目的。在C#或者其它的编程语言中,命令式编程是最为常见的:我们通过编写方法来定义程序的行为。我们可以通过C#中的属性来使用声明式编程。我们可以为类,...
imperative programming 是说定义执行的顺序,从这个角度来说跟 procedural programming 并没有区别,后者更多的是与 OOP 相对;而 imperative programming 更多的与 declarative programming 相对,主要是指只需要指定目标而不需要实现的那种。 functional programming 感觉比较 tricky,它其实是指程序通过定义类似 mathematical func...
