为什么打印矩阵结果和老师的不一样呢？

打印函数是这个：

void CMap::printMatrix()
{
for(int i=0;i<m_iCapacity;i++)
{
for(int k=0;k<m_iCapacity;k++)
{
cout<<m_pMatrix[i*m_iCapacity+k]<<" ";
}
cout<<endl;
}
}

主函数是这个：

int main(void)
{
	CMap *pMap=new CMap(8);
	
	Node *pNodeA=new Node('A');
	Node *pNodeB=new Node('B');
	Node *pNodeC=new Node('C');
	Node *pNodeD=new Node('D');
	Node *pNodeE=new Node('E');
	Node *pNodeF=new Node('F');
	Node *pNodeG=new Node('G');
	Node *pNodeH=new Node('H');
	
	pMap->addNode(pNodeA);
	pMap->addNode(pNodeB);
	pMap->addNode(pNodeC);
	pMap->addNode(pNodeD);
	pMap->addNode(pNodeE);
	pMap->addNode(pNodeF);
	pMap->addNode(pNodeG);
	pMap->addNode(pNodeH);
	
	
	pMap->setValueToMatrixForUndirectedGraph(0,1);
	pMap->setValueToMatrixForUndirectedGraph(0,3);
	pMap->setValueToMatrixForUndirectedGraph(1,2);
	pMap->setValueToMatrixForUndirectedGraph(1,5);
	pMap->setValueToMatrixForUndirectedGraph(2,4);
	pMap->setValueToMatrixForUndirectedGraph(4,5);
	pMap->setValueToMatrixForUndirectedGraph(3,6);
	pMap->setValueToMatrixForUndirectedGraph(3,7);
	pMap->setValueToMatrixForUndirectedGraph(6,7);

	
	pMap->printMatrix();
	
	cout<<endl;
	pMap->depthFirstTraverse(0);
	cout<<endl;
	
	pMap->resetNode();
	pMap->breadthFirstTraverse(0);
	
	system("pause");
	return 0;
}
