有如下程序: include using namespace std; class TestClass{ int k; public: TestCla

有如下程序:

include＜iostream＞

using namespace std;

class TestClass{

int k;

public:

TestClass(int x=1):k(x){}

～TestClass O{cout＜＜k;}

};

int main(){

TestClass a[]={TestClass(3),TestClass(3),TestClass(3)};

TestClass *p=new TestClass[2];

delete []p;

return ():

}

这个程序的输出结果是______。
