构造无参，出现1111.exe - 1 error(s), 0 warning(s)？这是什么情况？

Question

#include<iostream.h>
class AA
{
public:
AA(int i,int j)
{
A=i;B=j;
cout<<"Constructor.\n";
}
~AA(){cout<<"Destructor.\n";}
void print();
private:
int A,B;
};
void AA::print()
{
cout<<A<<","<<B<<endl;
}
void main()
{
AA a1,a2;
a1=new AA(1,2);
a2=new AA(5,6);
a1->print();
a2->print();
delete a1;
delete a2;
}
错误提示是：

两种办法，办法一，你在类里面添加如下无惨构造函数代码：AA(){}办法二，把这个AA(int&nbsp;i,int&nbsp;j)修改成带缺省参数的函数AA(int&nbsp;i=0,int&nbsp;j=0)&nbsp;&nbsp;然后把main函数修改如下：&nbsp;&nbsp;void&nbsp;main(){AA&nbsp;a1,a2;a1.rint();a2.print();}&nbsp;&nbsp;还有最简单的办法，直接把main函数修改如下：&nbsp;&nbsp;void&nbsp;main(){AA&nbsp;*a1,*a2;a1=new&nbsp;AA(1,2);a2=new&nbsp;AA(5,6);a1->print();a2->print();delete&nbsp;a1;delete&nbsp;a2;}

Answer 2

AA(int i,int j)你不是说要构造无参吗？怎么这个地方又有参数呢，看你标题知道你什么意思，但是看你程序就混啦…
