有以下程序：
include ＜iostream＞
using namespace std;
class sample
{
int x;
public:
void setx(int i)
{
x=i;
}
int putx ()
{
return x;
}
};
int main ( )
{
sample *p;
sample A[3];
A．[0] .set＞:(5);
A．[1] .setx(6);
A．[2] .setx(7);
for (int j=0;j＜3;j++)
{
p=&A[j];
cout＜＜p-＞putx () ＜＜", ";
}
cout＜＜end1;
return 0;
}
执行后的输出结果是[ ]。
