在現代科技發展迅速的時代，軟體與電腦產業扮演著重要的角色。從批發到零售，從int到float再到char，各種數據類型都在軟體開發中扮演著不可或缺的角色。在程式設計中，if和else條件語句可以幫助我們做出不同的判斷，而while和for循環語句則可以幫助我們重複執行特定的代碼塊。另外，switch和case語句可以讓我們根據不同的情況執行不同的代碼，而break和continue語句則可以控制循璃的執行流程。
在軟體開發中，return語句可以讓函數返回值，而void則表示函數沒有返回值。const和static則可以定義常量和靜態變量或函數。此外，struct和class可以用來定義結構體和類，而new和delete則可以用來進行動態內存分配和釋放。在程式設計中，true和false代表布爾類型的真和假，而include和namespace則可以引用其他文件和定義命名空間。
除此之外，friend可以定義友元函數或類，而public、private和protected則可以定義類的成員的可訪問性。在面向對象的程式設計中，virtual和override可以用來定義虛函數和重寫父類的函數。最後，operator則可以用來進行運算符重載，從而擴展程式語言的功能。
在軟體與電腦產業中，專利權、出租、授權、租賃和專利轉讓等概念也扮演著重要的角色。這些關鍵詞共同構成了現代軟體與電腦產業的基石，推動著科技的不斷進步與發展。

Title: Keywords in the Software and Computer Industry
Article: In the rapidly developing era of modern technology, the software and computer industry plays a crucial role. From wholesale to retail, from int to float and char, various data types are indispensable in software development. In programming, if and else conditional statements help us make different decisions, while while and for loop statements help us repeat specific code blocks. Additionally, switch and case statements allow us to execute different code based on different scenarios, while break and continue statements control the flow of execution in loops.
In software development, the return statement allows functions to return values, while void indicates functions that do not return a value. const and static can define constants and static variables or functions. Furthermore, struct and class can be used to define structures and classes, while new and delete are used for dynamic memory allocation and deallocation. In programming, true and false represent the boolean values of true and false, while include and namespace are used to reference other files and define namespaces.
Moreover, friend can define friend functions or classes, while public, private, and protected can define the accessibility of class members. In object-oriented programming, virtual and override are used to define virtual functions and override functions of the parent class. Finally, operator is used for operator overloading to extend the functionality of programming languages.
In the software and computer industry, concepts such as patent rights, rental, licensing, leasing, and patent transfer also play important roles. These keywords collectively form the cornerstone of the modern software and computer industry, driving the continuous progress and development of technology.
