Question

求救,急：VC++编程,类的编程,定义一个长方体类,可求解其表面积和体积

Answer 1

#include "stdio.h"

class rec

{

private:

int x,y,z;

int area,vol;

public:

rec(int a,int b,int c){x=a;y=b;z=c;}

void fun();

void show();

};

void rec::fun()

{

area=2*(x*y+y*z+z*x);

vol=x*y*z;

}

void rec::show()

{

printf("x:%iny:%inz:%inarea:%invol:%in",x,y,z,area,vol);

return;

}

int main()

{

rec a(1,2,3);

a.fun();

a.show();

}

建议你独立完成.代码已调试通过
