class - c++中不能用new创建一个类的对象数组？？

Question

include <iostream>

using namespace std;
class text
{
public:

text(int m,int n): a(m),b(n){}
int a;
int b;

};

int main()
{

**text *p=new text[2]**;/*用p指向创建的对象数组*/
...
return 0;

}

尝试用以上代码用new创建一个对象数组，发现不行，是哪里不对吗？
为什么用new又可以为结构体创建对象数组？

Answer 1

Try adding a parameterless constructortext(){}

Answer 2

Agree with Dappur's answer, you did not define a default constructor in the class. Your new text[2] statement was actually changed by the compiler to new text()[2], and it reported an error when it couldn't find it. I believe the compiler error says the same thing.
