java的问题建议去java板块问，发了好几个，其他的有人帮你移过了

#include <iostream>
#include<string>
using namespace std;
int main()
{
   string own[]={"zero","one","two","three","four","five","six","seven","eight","nine","ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen",
   "seventeen","eighteen","nineteen"};
   string  t[] = {"twenty", "thirty", "fourty", "fifty", "sixty",
                "seventy", "eighty", "ninty" };

             int tem{};


                cout<<"请输入数字\n ";

                cin>>tem;


                if(tem<20){cout<<own[tem];}

                else{

                    int shiwei=tem/10;
                    int gewei=tem%10;
                    if(gewei==0){cout<<t[shiwei-2];}
                    else{cout<<t[shiwei-2]<<"-"<<own[gewei];}
                    }
            }

请输入数字
 2
two
请输入数字
 13
thirteen
请输入数字
 45
fourty-five
请输入数字
 90
ninty

我看找蛙代码和C#有点像.
看代码有点疑惑为何限制为3,假如输入大于3?
        int m=sin.nextInt();
        int num[]=new int[m];
        for(int i=0;i<3;i++){
            num[i]=sin.nextInt();
        }
