#include <iostream.h>

public:

{
x=tx;
cout<<"call the constructor function FUNA!\n";
}
void print()
{ cout<<x<<"\n"; }
~ FUNA ()
{ cout <<"call the destructor function FUNA!\n"; }
};

class FUNB
{
int y;
public:

};

class FUNC

void show()
{
cout <<z<<"\n";
funa1.print();
funb1.print();
}
~ FUNC() {cout<<"call the desturctor function FUNC!\n"; }
};

FUNC:: FUNC (int tz,int tx,int ty): funb1(ty), funa1(tx)
{
z=tz;
cout<<"call the constructor function FUNC!\n";
}

void main()
{
FUNC func1 (10,20,30);
func1.show();
}

请问各位这个程序的流程是怎样的啊？？

===================================
call the constructor function FUNA!
call the constructor function FUNB!
call the constructor function FUNC!
10
20
30
call the desturctor function FUNC!
call the destructor function FUNB!
call the destructor function FUNA!
Press any key to continue

FUNC (int tz,int tx,int ty): funb1(ty), funa1(tx) 


调用顺序不取决于初始化的列表顺序，而是在类中对象定义的顺序！
