数组的动态申请.txt

层次聚类算法的c++实现

 struct test//二维数组的动态申请(1)
 {
	 float *m2;
 };
  test *m1;
	/m1 = new test[T+1];
	for(int ii1 = 0; ii1 < T+1; ii1++ )
	{
		m1[ii1].m2=new float[T+1];
	}



  float **m;   //二维数组的动态申请(2)
	m = (float**)malloc((T+1)*sizeof(float*));
	for(int ii = 0; ii < T+1; ii++ )
	{
		m[ii] = (float*)malloc((T+1)*sizeof(float));
	}



    float *mq;
	mq=new float[T+1];//一维数组的动态申请
