问题描述
嘿,我想在堆上分配一个动态矩阵,似乎我做错了。
我试着做以下事情:
vector< vector< int *> > * distanceMatrix = new vector< vector< int *> > ;;
它在堆上分配一个矩阵,但矩阵本身为空,我想要矩阵为sizeXsize,但不能单独排序
尝试使用
向量< vector< Distance *> >感谢您的帮助
hey, i am trying to allocate a dynamic matrix on the heap and seems like i am doing something wrong.i try to do the following thing :
vector< vector<int*> >* distancesMatrix=new vector< vector<int*> >;
it does allocate a matrix on the heap but the matrix itself is empty, i want the matrix to be sizeXsize but cant sort it alonewhen not trying to allocate it on the heap with using vector<vector<Distance*> > distance(size+1, vector<Distance*>(size+1, NULL));
thanks for your help
推荐答案
尝试
vector< vector< int> >(size,size)
。
