给出下面程序的输出结果

#include ﹤ iostream ﹥

using namespace std;

template ﹤ class T ﹥

T F(T x)

{

return x ﹥ 5;

}

void main( )

{

int a = 15;

cout ﹤﹤ F(a) ﹤﹤"\n";

double b = - 5.8976;

cout ﹤﹤ F(b) ﹤﹤" \n";

cout ﹤﹤ F(5) ﹤﹤" \n";

}

定义队列类模板queue(先进先出)，队列的大小由使用者确定。要求该类模板对外提供如下二种基本操作：(1)inser(入队列)(2)front(出队列)，用数组来实现

#include ﹤ iostream ﹥

using namespace std;

template ﹤ class T, int size ﹥

class queue {

T x [ size ] ;

int current, front, rear;

public:

queue ( ) { current = 0; front = 0; rear = 0;}

....insert(....);

....front(....);

};

请写出两个函数的过程(如果需要形式参数，请给出形参类型和数量，以及返回值类型)

给出下面程序的输出结果

#include ﹤ iostream ﹥

using namespace std;

template ﹤ class T ﹥

T F(T x)

{

return x ﹥ 5;

}

void main( )

{

int a = 15;

cout ﹤﹤ F(a) ﹤﹤"\n";

double b = - 5.8976;

cout ﹤﹤ F(b) ﹤﹤" \n";

cout ﹤﹤ F(5) ﹤﹤" \n";

}

给出下面程序的输出结果

#include ﹤ iostream ﹥

using namespace std;

class A

{

private: int X, Y;

public: A ( int myx, int myy) { X = myx; Y = myy ;}

void show ( ) { cout ﹤﹤ "X =" ﹤﹤ X ﹤﹤ " Y = " ﹤﹤ Y ﹤﹤ endl;}

};

class B : public A

{

private : int H, W;

public: B( int myx,int myy,int myh,int myw): A( myx, myy)[H=myh;W=myw;}

void show ( ) { cout ﹤﹤ "H = " ﹤﹤ H ﹤﹤ " ; W = " ﹤﹤ W ﹤﹤ endl; }

};

void main( )

{

B d(1,2,3,4) ;

d. show ( ) ;

}

下列程序将x，y，z按从小到大的顺序排列并将结果返回给实参，在横线处填入正确的内容。template ﹤ class T ﹥

void order(_________)

{

_________;

if(x ﹥y) {a =x;x =y;y =a;}

if(y ﹥z) {a =y;y =z;z =a;}

if(x ﹥y) {a =x;x =y;y =a;}

}

在下面程序的下划线处填上正确的语句。

#include ﹤ iostream ﹥

using namespace std;

template ﹤ class T ﹥

T f( T&a, T&b, int n)

{

for (int i=0;i ﹤n;i ++ )

a[i] =a[i] +b[i];

return a ;

}

void main( )

{

int a[5] ={1,2,3,4,5};

int b[5] = { 100,200,3,4,51 , * p;

for(int i =0; i ﹤2; i ++)p=_________ //调用函数f

for( ; p ﹤a +5; p ++ )

cout﹤﹤_________﹤﹤endl;

}

完成下面程序中的show函数的定义，使其运行结果如下：In baseIn derived程序清单如下：

#include ﹤ iostream ﹥

using namespace std;

class base

{

pubhc :

virtual void print( )

{

cout ﹤﹤ "In base" ﹤﹤ endl;

}

};

class derived: public base

{

public :

void print( ) { cout ﹤﹤ "In derived" ﹤﹤ endl; }

};

void show(base * pb, void (base:: * pf) ( ) )

{

_________

}void main( )

{

base b;

derived d;

show ( &b, base::print);

show ( &d, base::print);

}

在下面程序的下划线处填上正确的数据类型，保证程序具有如下输出结果：

0

17

17，17，17

源程序如下：

#include ﹤ iostream ﹥

using namespace std;

class base{

public:

______________num;

base ( ) { }

};

int base::num = 0;

void main( ){

cout ﹤﹤ base::num ﹤﹤ endl;

_______________* p=&base::num;

*p=17;

cout ﹤﹤ base::num ﹤﹤ end1;

base a,b;

cout ﹤﹤ *p﹤﹤"," ﹤﹤ a. num ﹤﹤ "," ﹤﹤b. num;

}

在下面横线处填上正确的内容，完成类的定义。

class Base

{

int x;

static const int b;

public:Base( int, int);

const int &a;

};

______________b =15;

Base::Base(int i,int j): ___________{ }

#include ﹤ iostream. h ﹥

void main( ) {

string str1 (" we are here" );

cout ﹤﹤ str1 ﹤﹤ endl;

}

#include ﹤ iostream. h ﹥

class point

{

private: float x, y ;

public: f( float a, float b) { x = a; y = b ; }

f( ) {x=0; y=0;}

void getx( ) { cout ﹤﹤ x ﹤﹤ endl; }

void gety ( ) { cout ﹤﹤ y ﹤﹤ endl ; }

}

class pointl

{

private: float x, y;

public: f( float a, float b) { x = a; y = b ; }

f( ){x=1; y=1;}

void getx( ) {cout ﹤﹤x ﹤﹤endl;}

void gety( ) {cout ﹤﹤y ﹤﹤endl;}

};

main( ) {

point a;

a.f( );

a. getx( );

a. gety( );

}
