C++編程編寫函數fun()

void fun(double*x,double*y,double*z,double*sum,double*sub)

{

*sum=*x>*y?*x:*y;

*sum=*sum>*z?*sum:*z;

*sub=*x<*y?*x:*y;

*sub=*sub<*z?*sub:*z;

}

int main()

{

double a,b,c,max,min;

printf("請輸入三個浮點數：");

scanf("%lf %lf %lf",&a,&b,&c);

fun(&a,&b,&c,&max,&min);

printf("最大為：%1.2lf\n",max);

printf("最小為：%1.2lf\n",min);

return 0;

}

c語言書面作業。。。
