#include

class Time

{public:

Time(char*s=NULL);

void operator+(Time&ti);

void operator-(Time&ti);

void Display();

Protected:

int hour;

int minute;

int second;

};

#include

#include

using namespace std;

class complex

{public:

int real;

int imag;

complex(int r=0, int i=0)

{real=r;

imag=i;

}

};

complex operator+(___________,complex& b)

{int r= a.real +b.real;

int i=a.imag +b.imag;

return___________;

}

void main()

{complex x(1,2),y(3,4),z;

z=x+y;

cout<

输出数组中的最小数。

#include

void main()

{int a[]={34,91,83,56,29,93,56,12,88,72};

int index=0;

int/sizeof(*a);

for(int i=l;i

{if(a[index]>a[i])

____________

}

cout<<"a数组最小数:"<

}

给出下面程序的输出结果。

#include

class A

{int*a;

public:

A(int x=0):a(new int(x)){}

~A(){deletea;}

int getA(){return*a;}

void setA(int x)*a=x;}

};

void main()

{A x1,x2(3);

A*p=&x2;

(*p).setA(x2.getA()+5);

x1.setA(10+x1.getA());

cout<

}

请在下面程序的横线处填上适当内容,以使程序完整,并使程序的输出为:

11,10

13,12

#include

class A

{int a;

public:

A(int i=0){a=i;}

int Geta(){return a;}

void show(){cout<

};

class B

{A a;

int b;

public:

B(int i,int j)__________

{}

void show(){cout<

};

void main()

{B b[2]=B(10,11),B(12,13)};

for(int i=0;i<2;i++)

____________

}

程序的输出结果如下:

m=4.3,n=3

m=6,n=9

请根据输出数据在下面程序的横线处填写正确的语句。

#include

class Test

___________

{private:

T1 m,n;

public:

Test(T1 i,T1 j){m=i;n=j;}

void show(){cout<<"m="<

};

void main()

{Testa(4.3,3);

a.show();

___________b(6,9.6);

b.show();}

#include

int getx(){return x;}

int gety(){return y;}

};

void main()

{Test mt(10,20);

cout<

cout<

for(int j=0;j<5;j++)

p[j].Setij(j,j);

for(int k=0;k<5;k++)

cout<<"Muti["<

_________

return 0;

}

下面程序的功能是生成具有n个元素的动态数组。

#include

void main()

{int n;

cin>>n;

int a[n];

a[0]=2;

cout<

}
