代码如下：

class Recangle{

private:

int width;

int length;

public:

Recangle()

{width = 0; length = 0;};

Recangle(int w,int h)

{width = w; height = h;};

int circumference()

{return 2*(width+height)};

int Area()

{return width * height};

void changeRec(int w, int h)

{width = w; height = h;};

};

C++编程如下

#include <iostream.h>

#include <std.h>

#include <math.h>

int main()

{

int a1=5,a2=6;

int b1=4,b2=5;

int s1,s2;

s1=a1*a2;

s2=b1*b2;

printf("矩形1的面积为：%d;",s1);

printf("矩形2的面积为：%d;",s2);

if(s1>s2)

{

printf("s1>s2");

}

else

{

if(s1<s2)

{

printf("s1<s2");

}

else

{

printf("s1=s2");

}

}
