C++的动态多态和静态多态

多态是C++中面向对象技术的核心机制之一,包含静态多态和动态多态,它们之间有一定的相似性,但是应用范围不同。该文论述了这种相似性,并重点论述了以模板实现的静态多态的应用范围。

多态在C++程序设计中的作用及实现

论文阐述了多态性在面向对象程序设计中的作用,使用方法及实现过程。通过具体程序实例重点叙述虚函数在动态多态实现时的使用方法。

C++语言程序设计中多态问题分析

C++语言程序设计课程中,多态性分为两类。一是静态多态,通过函数重载实现,解决自定义数据类型运算问题;二是动态多态,通过虚函数实现,提高了程序的可扩充性。通过实例分析出利用函数重载实现静态多态的方法以及利用虚函数产生动态多态的条件。

C++语言的函数多态性在程序设计中的应用

本文试从C++语言的函数静态多态性和动态多态性两方面,探讨多态性在C++程序设计中的运用。

Static and dynamic collaborative optimization of ship hull structure

The goal of this effort was to provide a static and dynamic collaborative optimization （CO） model for the design of ship hull structure. The CO model integrated with static, mode and dynamic analyses. In the system-level optimization model, a new objective function was advised, integrating all the subsystem-levels＇ objective functions, so as to eliminate the effects of dimensions and magnitude order. The proposed CO architecture enabled multi-objectives of the system and subsystem-level to be considered at both levels during optimization. A bi-level optimization strategy was advised, using the multi-island genetic algorithm. The proposed model was demonstrated with a deck optimization problem of container ship stern. The analysis progress and results of example show that the CO strategy is not only feasible and reliable, but also well suited for use in actual optimization problems of ship design.
