C中的三维向量++
原标题:three dimensional vectors in C++

我的c++代码中有:

  typedef vector<int> cards;
  typedef vector<cards> rows;
  typedef vector<rows> matriz;

在我的int main()中,我尝试用这行初始化一个名为“cartas”的matriz;

  63  cin>>n>>m;
  66  cartas(n,rows(m, cards(0)));

但是,对于g++,请删除以下错误:

flip.cpp: In function ‘int main()’:
flip.cpp:66: error: no match for call to ‘(matriz) (int&, rows)’

我想取一个n*m矩阵,其中每个位置都有整数向量。

谢谢,现在,我不明白怎么回事。

最佳回答

你的代码是否与以下代码相似:

int n, m;
matriz cartas;
cin>>n>>m;
cartas(n,rows(m, cards(0)));

?

这行不通,马莉兹·卡塔斯已经是一个初始化。要么在cin语句后定义cartaz

最优的

int n, m;
cin>>n>>m;
matriz cartas(n,rows(m, cards(0)));

可供替代的

int n, m;
matriz cartas;
cin>>n>>m;
cartas = matriz(n,rows(m, cards(0)));
问题回答

Why not just set an array of size n*m vector[]. you can get each row as index % n and column as index % m. Much simpler and cleaner.
