23．下面程序的运行结果是________。
#include "iostream.h"
class test
{
private:
int num;
float fl;
public:
test( );
int getint( ){return num;}
float getfloat( ){return fl;}
~test( );
};
test::test( )
{
cout << "Initalizing default" << endl;
num=0;fl=0.0;
}
test::~test( )
{
cout << "Desdtructor is active" << endl;
}
void main( )
{
test array[2];
cout << array[1].getint( )<< " " << array[1].getfloat( ) <<endl;
}
希望有点过程，谢谢。。。

Initalizing default

Desdtructor is active
Desdtructor is active
执行到test array[2];时,因为是两个,所以连续调用两次构构造函数test()
然后就是你所写出的cout << array[1].getint( )<< " " << array[1].getfloat( ) <<endl输出；
这时main()函数快要结束．所以你定义的两个test对象要被撒毁，所以调用了你定义的析构函数～test()
