再开一贴，还有2道题需要解答，今天就结贴！！

[littleboys]

程序设计题，定成C++程序
1 从键盘输入二个任意大小的数，在屏幕上从小到大输出这二个数。
［程序：］


2 首先（1）定义一个基类“建筑物”（building）,私有段有楼房层数fr,房间数r,楼房总面积m,有构造函数。
（2）从基类building定义派生类“住宅楼”（house）,有卧室数量br,浴室数量dr,有构造函数，能显示住宅楼所有数据。
（3）在主函数中定义住宅楼对象，其楼房层数\房间数\楼房总面积\卧室数量和浴室数量分别为10，200，30000，500，300，并显示住宅楼所有数据。
（应严格按照题目要求定义类）

第一个

#include <iostream>
using namespace std;
int main ( )
{
	int a,b;
	cout<<"输入两个整数:"<<endl;
	cin>>a>>b;
	if (a>b)
		cout<<a<<' '<<b<<endl;
	else
		cout<<b<<' '<<a<<endl;
	return 0;
}

[mengde007]

#include <iostream>
int main()
{
 int a,b;
 cin>>a>>b;
 if(a>b)
 {
 cout<<a<<b<<endl;
 }
 else
 cout<<b<<a<<endl;
return 0;
}

[mengde007]

#include <iostream>
using namespace std;
int main()
{
 int a,b;
 cin>>a>>b;
 if(a>b)
 {
 cout<<a<<b<<endl;
 }
 else
 cout<<b<<a<<endl;
return 0;
}

算了，不写了，机会留给别人吧

1:

int main() 
{ 
    int a,b,cmp;
	cin>>a>>b;
	if(a>b)
	{
		cmp=a;
		a=b;
		b=cmp;
	}
	cout<<a<<" "<<b<<endl;

    return 0; 
}

想写，但又感觉太简单了浪费时间……

嘿嘿，帮忙写一下第二个吧。

２.

class building

	int r;
	float m;
public:
	building(int fr_c=0,int r_c=0,float m_c=0):fr(fr_c),r(r_c),m(m_c){};

	cout<<h.get_br()<<endl;
	cout<<h.get_fr()<<endl;
	//....

    return 0; 
} 

[fibbery]

写一个不用比较的按照从小到大输出a、b的代码：

#include <iostream>
#include <math.h>

int main(int argc, char * argv[])
{
   int a,b;
   std::cin>>a>>b;
   std::cout<<((a+b)-abs(a-b))/2<<" "<<((a+b)+abs(a-b))/2<<std::endl;
   return 0;
}

[xqls_xqls]

#include <iostream>
using namespace std;

class building{
public:
int fr;
int r;
int m;
building(int fr1=0,int r1=0,int m1=0){
fr = fr1;
r = r1;
m= m1;
}
};

class house:public building{
public:
int br;
int dr;
house(int fr1=0,int r1=0,int m1=0,int br1=0,int dr1=0):building(fr1,r1,m1){
br=br1;
dr=dr1;
}
void show(){
cout<<"房层数: "<<fr<<endl
<<"房间数: "<<r<<endl
<<"楼房总面积: "<<m<<endl
<<"卧室数量:"<<br<<endl
<<"浴室数量:"<<dr<<endl;
}
};

void main()
{
house ho(10,200,30000,500,300);
ho.show();
}
