调整多维向量的大小

Question

如何调整多维向量的大小,例如:

  vector <vector <vector <custom_type> > > array; 

例如,我需要数组[3] [5] [10]？

Answer 1

array.resize(3,vector<vector<custom_type> >(5,vector<custom_type>(10)));

Answer 2

我做的))

array.resize(3);
for (int i = 0; i < 3; i++)
{
    array[i].resize(5);
    for (int j = 0; j < 5; j++)
    {
       array[i][j].resize(10);
    }
}

Answer 3

另见Boost.MultiArray

Boost.MultiArray provides a generic N-dimensional array concept definition and common implementations of that interface.

Answer 4

您应该vector一一调整所有嵌套的大小。使用嵌套for循环或递归。
