電腦是現代科技發展中不可或缺的一部分。電腦週邊設備和周邊配件給電腦帶來了更多功能和擴展性。電腦零售店提供各種各樣的電腦產品，包括硬體和軟體，讓消費者有更多選擇。int和float是常見的數據類型，用於存儲整數和浮點數。而char則用於存儲字符數據。在編程中，if和else語句用於控制程序的流程，根據條件執行不同的代碼。while和for循環則用於重複執行代碼塊。在多重選擇語句中，switch和case可以讓程序根據不同的情況執行不同的代碼。break用於終止循環或多重選擇語句，而continue則跳過當前迭代。return則用於返回函數值。const和static用於定義常量和靜態變量或函數。struct和class定義了結構體和類，而new和delete則用於動態內存分配和釋放。在編程中，真值和假值分別用true和false表示。另外，include和namespace可以用來引用其他文件和定義命名空間。使用friend可以定義友元函數或類，而public、private和protected則指定了類成員的訪問權限。虛函數可以通過virtual和override來實現，運算符重載則可以通過operator來定義。

Computer peripherals and accessories bring more functionality and expandability to computers. Computer retail stores offer a variety of computer products, including hardware and software, providing consumers with more choices. int and float are common data types used to store integers and floating-point numbers, while char is used to store character data. In programming, if and else statements control the flow of programs, executing different code based on conditions. while and for loops are used to repeatedly execute code blocks. In multiple-choice statements, switch and case allow programs to execute different code based on different scenarios. break is used to terminate loops or multiple-choice statements, while continue skips the current iteration. return is used to return function values. const and static are used to define constants and static variables or functions. struct and class define structure and classes, while new and delete are used for dynamic memory allocation and deallocation. In programming, true and false represent boolean values. Additionally, include and namespace are used to reference other files and define namespaces. Using friend, you can define friend functions or classes, and public, private, and protected specify the access rights of class members. Virtual functions can be implemented using virtual or override, while operator can be used to define operator overloading.
