模拟题,

提交时,要支持iostream同时使用long long则应选g++.

Source:

#include<iostream>

#include<string>

using namespace std;

 

char word[220]="negative,zero,one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve,thirteen,fourteen,fifteen,sixteen,seventeen,eighteen,nineteen,twenty,thirty,forty,fifty,sixty,seventy,eighty,ninety,hundred,thousand,million";

int val[220];

 

int main()

{
