Question

Answer 1

include"iostream"
using namespace std;

void main()
{
    int a,b,c,i,n1,n2;

    n1=n2=0;
    for( i=100; i<=999; i++ )
    {
        c=i%10;
        b=(i-i%10)/10%10;
        a=i/100;
        if( i == a*a*a+b*b*b+c*c*c )
        {
            n1=n2;//n1是次大值，n2是最大值
            n2=i;
        }
    }
    cout<<"水仙花的次大值是："<<n1<<endl;
}
