矢量和Carray之间的区别 [英] Difference between vector and Carray

问题描述

std :: vector< mtpoint2d> m_Points;



CArray< MtPoint2d，Mtpoint2d> m_Points





以上声明是否相同？



如果我给std :: vector< mtpoint2d mtpoint2d => m_Points;作为CArray它给我错误...



请让我知道

解决方案

std :: vector 和 CArray 是两个不同的容器。它们可能服务于相同的目的，但它们不可互换（它们的公共接口不同）。如果可以，请使用 std :: vector ，因为它更好。



[update]

您也可以使用

 CArray< MtPoint2d，MtPoint2d> 

或a

 std :: vector< MtPoint2d> 

出于同样目的。

[/ update]

 CArray <     class    ，    class    >  point 
 
 A类:: A（const A& point2Array）
 {
 
 point.Copy（point2Array.m_Points）; //使用Carray 
 
如何处理向量
} 

请让我知道如何处理vector

std::vector <mtpoint2d> m_Points;

CArray < MtPoint2d , Mtpoint2d > m_Points


are both the above declartions are same?

if i give std::vector <mtpoint2d mtpoint2d=""> m_Points; as CArray its giving me error ...

Please let me know

解决方案

The std::vector and the CArray are two different containers. They may server the same purpose, however they are not interchangeable (their public interface is different). If you can, use std::vector, since it is better.

[update]
You may alternatively use a

CArray < MtPoint2d, MtPoint2d > 

or a

std::vector < MtPoint2d > 

for the same purpose.
[/update]

CArray < class , class > point

Class A::A(const A &point2Array)
{

    point.Copy(point2Array.m_Points); //working with Carray

    how to do with vector
}

please let me know how to do with vector
