题目描述
英语是现在世界第一大语言,所以学好英语是very important,
但是宁波大学的某个大牛说:“我不怕,我可以写一个程序让各种语言
快速转换。”哎呀,学编程的,惹不起...溜...┈━═☆
咱不是大牛,但有追逐大牛的梦想,大牛的伟大程序不是随便能盗版出来的,
我们就做一个简单的翻译器,把阿拉伯数字转换为英文输出。
输入要求
小于10000的非负阿拉伯数字整数n。
输出要求
对应的英文,如样例,一个一行。
测试数据
//输入
3923
5021
//输出
three thousand nine hundred twenty three
five thousand twenty one
AC代码
折磨人的代码,多棒 = =
- 考虑好10-19,11是eleven,不是ten one
- 注意输入0 也要输出zero,而不是什么都不输出
- 其他照旧
#include <bits/stdc++.h>
using namespace std;
int main() {
string in,res[10]={"zero","one","two","three","four","five","six","seven","eight","nine"};
string shi[10]={"","ten","twenty","thirty","forty","fifty","sixty","seventy","eighty","ninety"};
string shi2[10]={"ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen","seventeen","eighteen","nineteen"};
int f,num;
while(cin>>in)
{
if(in.size()==1) //个位数单独考虑
{
cout<<res[in[0]-'0']<<endl;continue;
}
f=0;
// 输出千位和百位,如果没有则不用输出
for(int i=0;i<in.size()-2;i++)
{
if(in[i]=='0') continue;
if(f) cout<<" ";f=1;
cout<<res[in[i]-'0'];
if(in.size()-i==4) printf(" thousand");
if(in.size()-i==3) printf(" hundred");
}
// 输出十位和个位
num=(in[in.size()-2]-'0')*10+in[in.size()-1]-'0';
if(num>=10 && num<=19)
{
if(f) cout<<" ";f=1;
cout<<shi2[num-10];
}
