有以下程序: include using namespace std; class sample {int x; public:void setx(

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[ ]。
