数据抽象(Data Abstraction) 有限,只能通过结构体(Structures)和数组(Arrays)等方式 高级,通过类(Classes)和访问修饰符等机制进行封装(Encapsulation) 标准库(Standard Library) 标准C库,主要包括输入输出和数学函数等 包含标准C库,并拓展了STL、输入输出库(iostream)、多线程支持库(thread)、时间库(chrono)等 内存管理...

2.2.1 Classes The concept of class is the principal means of data encapsulation and abstraction in C++. You can think of a class as a structure with functions. In fact, in C++ struct is only a special case of class. The relation of class to object is that of a data type to a varia...

SystemC®[29] is used for both simulation of hardware providing for simulation performance benefits overRTLlevelVerilog®-HDL or VHDL design descriptions and forfunctional verification. In ...
In the same way that CPython makes it easy to import C libraries and use them from Python, Jython makes it easy to import and reference Java modules and classes. The Python Language Specification Contained within the CPython source code is the definition of the Python language. This is the...
all child classes. What an abstract class can _also_ do, though, is declare methods and properties that will be supplied by all child classes, but defer the actual code to the child class, in effect saying, "Every one of my children must have this method, but I'm not supplying any ...
Many design project teams and research and development groups are working to significantly reduce system verification runtimes and perform system verification earlier in the design process. One solution successfully being used to address both issues at once is the creation of higher abstraction models of...
In order to create our own context switching package, we need to inherit from sc_cor_pkg and sc_cor classes. The following sections show a part of our implementation. 4.2.1 sc_cor_pkg_ucontext We describe here the implementation of the sc_cor_pkg_ucontext, which inherits from...
