如何从数组传递到vector - c ++(How to pass from array to vector - c++)

我是c ++编程的新手,我试图更好地理解数组和向量之间的差异。 在我的程序中,我有一个类Graph,其中一些数组作为私有成员。 该类有一个方法,使用这些数组实现最小生成树的Prim算法。 我从这个页面中取出算法并将其更改为我的程序。

我现在被要求使用向量而不是数组,所以我想知道:

我真的需要改变多少东西? 声明和构造函数,好的。 但循环,初始化。 我必须改变一切吗? 该计划无论如何都有效。 使用向量函数是否如此重要?


I'm new in c++ programming and I'm trying to understand better the differences between array and vector. In my program I've got a class Graph with some arrays as private members. The class has a method that use these arrays to implement the Prim's algorithm for minimum spanning tree. I took the algorithm from this page and changed it for my program.

I am now asked to use vectors instead of arrays so I would like to know:

How many things do I really have to change? The declaration and the constructors, ok. But the cycles, the initializations. Do I have to change everything? The program works anyway. Is it so important to use vector's function?

最满意答案

事实证明,跟踪器名称中的破折号导致它无法正常工作。 切换到跟踪器名称的camelBack外壳修复了问题。 就我所见, 目前的文档中没有关于允许字符的内容 。 看起来只是字母和数字应该是安全的 - 即通过/ ^ [0-9a-zA-Z] + $ / regex。


Turns out, it was the dashes in the tracker name that caused it to not work. Switching to camelBack casing for the tracker name fixed the problem. There is nothing about allowed characters in the current documentation as far as I have seen. It seems just letters and numbers should be used to be safe - i.e. one that passes a /^[0-9a-zA-Z]+$/ regex.
