向量作为C ++中的数据成员 [英] vector as a Data Member in C++

问题描述

在C ++中，如何在我的类中包含101个元素向量作为数据成员？我正在做以下，但它似乎不工作：

In C++, how do I include a 101 elements vector as a data member in my class? I'm doing the following, but it doesn't seem to be working:

private:
    std::vector< bool > integers( 101 );

我已经包含了向量头。提前致谢！

I already included the vector header. Thanks in advance!

推荐答案

class myClass {
    std::vector<bool> integers;
public:
    myClass()
        : integers(101)
    {}
};

我也喜欢 std :: array 理念。如果你真的不需要这个容器在运行时改变它的大小，我建议使用固定大小数组选项

I also like the std::array idea. If you really don't need this container to change it's size at run-time, I will suggest going with the the fixed size array option
