问题描述

嗨

谁能说出c ++和pascal中多态性的区别.

谢谢.

Hi

Can anybody say me the difference of polymorphism in c++ and pascal .

Thank you .

推荐答案

Pascal基本上是单态的:您无法定义多态函数或过程.但是，某些内置函数是多态的(例如+，-，*和/).但是，FORTRAN也是如此，因此它并不是一个很好的例子！

这里有一个讨论此问题的文档: http://webcourse .cs.technion.ac.il/234319/Spring2007/ho/WCFiles/05-Polymorphism.pdf [

Pascal is basically monomorphic: you can''t define polymorphic functions or procedures. However, some of the built in functions are polymorphic (+, -, * and / for example). However, this is also true of FORTRAN so it isn''t really a good example!

There is a document here which does talk about this: http://webcourse.cs.technion.ac.il/234319/Spring2007/ho/WCFiles/05-Polymorphism.pdf[^] Search for Pascal and you will see.
