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

Answer 1

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 i,int j)修改成带缺省参数的函数AA(int i=0,int j=0)  然后把main函数修改如下：  void main(){AA a1,a2;a1.rint();a2.print();}  还有最简单的办法，直接把main函数修改如下：  void main(){AA *a1,*a2;a1=new AA(1,2);a2=new AA(5,6);a1->print();a2->print();delete a1;delete 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…
