终于有了间茅草棚

不借助编译器，说出下面程序的输出。

程序片断一： 
#include <iostream>
class base
{
public:
    void fun( double value )
    {
        std::cout << value << std::endl;
    }
};
class derive : public base
{
public:
    void fun( int value )
    {
        std::cout << value << std::endl;
    }
};
int main( int argc,char *argv[] )
{
    derive d;
    d.fun( 1 );
    d.fun( 1.5 );
    return 0;
}

程序片断二：
#include <iostream>
class base
{
public:
    virtual void fun( void )
    {
        std::cout << "In base" << std::endl;
    }
};
class derive : public base
{
public:
    virtual void fun( void )
    {
        std::cout << "In derive" << std::endl;
    }
};
int main( int argc,char *argv[] )
{
    base *pBase = new derive;
    pBase->fun();
    base &rBase = *pBase;
    rBase.fun();
    return 0;
}
