很久没写C++代码了，访问权限这块可能有问题，你自己改改就行。
public class Num
{
public Num()
{
real = 0;
img = 0;
}
public Num(int x,int y)
{
real = x;
img = y;
}
private int real;//实部
private int img;//虚部
public void setReal(int x)
{
real = x;
}
public void setImg(int y)
{
img = y;
}
public int getReal()
{
return real;
}
public int getImg()
{
return img;
}
public void displayNum()
{
cout<<"该复数为："< }
}

2个数组不行吗？
