.NET Framework主要包含一个庞大的代码库,可以在客户语言中通过面向对象编程技术(OOP)来使用这些代码。这个库分为多个不同的模块,这样就可以根据希望得到的结果来选择使用其中的各个部分。例如,一个模块包含Windows应用程序的构件,另一个模块包含网络编程的代码块,还有一个模块包含Web开发的代码块。一些模块还分为更具体的子

6-13:使用动宾词组为执行某操作的函数命名。如果是OOP方法,可以只有动词(名词是对象本身)。 示例:参照如下方式命名函数。 voidprint_record( unsigned int rec_ind ) ; intinput_record( void ) ; unsignedchar get_current_color( void ) ; 6-14:避免使用无意义或含义不清的动词为函数命名。 说明:避免用含...

Fundamental OOP concept. The capability of a class to derive properties and characteristics from another class.C++20#include <iostream> class human { public: int height; int weight; public: human(int h, int w) { height = h; weight = w; } int get_height() const { return height; } ...
C++ is an enhanced version of C. C++ includes all aspects of C and adds support for object-oriented programming (OOP). C++ also contains many improvements and features that make it a “better C,” independent of OOP. The C++ language is extensible: We can define new types in such a way...
代码例子(Code examples) 12 . 下面的代码输出是什么,为什么? void foo(void) { unsigned int a = 6; int b = -20; (a+b > 6) puts("> 6") : puts("<= 6"); } 这个问题测试你是否懂得C语言中的整数自动转换原则,我发现有些开发者懂得极少这些东西。不管如何,这无符号整型问题的答案是输出是...
OOP 中对象的基本特征之一是其状态。通过向对象发送消息(换句话说,调用它的方法)来修改对象的状态在 OOP 中至关重要。通常,成员函数调用会导致对象状态的修改。在函数式编程中,我们将代码组织成纯函数的集合,每个函数都有自己的目的,并且独立于其他函数。 让我们看一个简单的例子,只是为了让这个概念清晰。假设我们...
You’re building a C program. You want to iterate through the code multiple times, but you don’t want to just copy and paste it. What can you do to keep your code as condensed and maintainable as possible while still running it multiple times?
/* My first C program */ printf("I can program in C! \n"); return 0; } Note the inclusion of the stdio.h file so that we can access the printf function and note the curly brackets to show that this is a single code block. The stdio file is an acronym for “standard input/ou...
