Simple question about list of one dimensional arrays.

[yeye_olive]

If your arrays will always have the same length (6 in your example), then you could use std::array instead of QVector:

#include <array>
typedef std::array<int, 6> MyArray;
 
QList<MyArray> l;
l.push_back(MyArray{0, 1, 2, 3, 4, 5});

#include <array>
typedef std::array<int, 6> MyArray;

QList<MyArray> l;
l.push_back(MyArray{0, 1, 2, 3, 4, 5});

This is C++11, but if you use an older version you can define your own MyArray by wrapping a plain C array in a class. std::array has the following advantages over QVector:

• the fixed length (6) of all the arrays is enforced by typing;
• std::array is more memory-efficient, because it does allocate extra storage in case the array grows, like QVector does;
• there is no extra indirection (although QVector could implement a small array optimization).
