与构造对象的数组 [英] Array of objects with constructor

问题描述

我有一个名为类小说。下面提到我可以声明对象数组：

 小说OBJ;
 

但问题是小说的构造函数，我想叫的我怎么能做到这一点数组的所有索引。我试着以下，但它不工作。

 小说OBJ（I，N）[2];
 

解决方案

您需要使用一个使用动态分配推迟单个元素的结构的适当的容器中。

 的std ::矢量＆lt;＆新GT; OBJ文件（2，新型（I，N））;

I have class named Novel. I can declare array of objects as mentioned below:

Novel obj;

but problem is Novel has constructor which I want to be called for all indexes of array how can I do that. I tried following but it does not work.

Novel obj(i,n)[2];

解决方案

You need to use a proper container that uses dynamic allocation to defer construction of individual elements.

std::vector<Novel> objs(2, Novel(i,n));
