初学者,呵呵~~请问这个程序有什么问题?

这个是很重要,我以后会记住的,谢谢!
但是现在我delete了,为什么还是不行?

作了简单地修改，请参考：
#include <iostream.h>

#define SIZE 10

//const int SIZE=10;
class stack
{
int * data;
int tos;
public:
stack ();
~stack ();
void push ( int a );
};

stack::stack ()
{
tos = 0;
data = new int[SIZE];
cout<<"hello!"<<endl;
}
stack::~stack ()
{
delete data;
cout<<"bye!"<<endl;
}
void stack::push ( int a )
{
if ( tos == SIZE )
{
cout<<"the stack is full!"<<endl;
return;
}
else
{
data[tos] = a;
++tos;
cout<<"input "<<a<<endl;
}
}

int main ()
{
stack obj;

for( int i = 0 ; i < SIZE + 1 ; i++ )
obj.push ( i );

return 0;
}
