C++图的邻接矩阵模板类

• 简单实现图的邻接矩阵,头文件如下

#pragma once
#include <iostream>

using namespace std;

template<class T>
class MatriGraphx
{
   
   
public:
	MatriGraphx(size_t capacity = 20);
	~MatriGraphx();

	class Vertex//顶点
	{
   
   
	public:
		Vertex(T v) {
   
    val = v; }
		friend class MatriGraphx<T>;
	private:
		T val;
	};
public:
	void addVertex(T);//增加顶点
	void addEdg
