//c++ 通話費計算

。題目:
有一家電信公司的計費方式:
每個月打800分鐘以下(不含800)，每分鐘0.5元;
打800-1500分鐘時，所有電話費以95折計算;
打1500分鐘以上(不含1500)，則通話費以8折計算。
請寫出一個程式，可由使用者輸入通話分鐘，程式即輸出其費用。

鈴

「鈴!鈴!」

微風輕搖窗邊的晴天娃娃造型的風鈴，小二那年我父親送我的生日禮物。

在這溫度恰到好處的春日早晨，我坐於書桌前，緩緩地翻著小時的札記，從前的歡樂浮出了紙張，不斷地，不斷地，席捲著我的心頭。透過窗戶灑進來的晨陽，在玻璃的折與反，映射出了絢爛的霓虹世界，成了我回憶裡的夢幻。隨著風輕拂的花兒，華麗地揮灑著身上的露珠，與青草地彈奏曲曲柔和的旋律，繞於身旁。

彷彿，獨自乘著一艘小帆。徜徉於汪洋，隨著波浪的起舞享受自然的韻律。遠方，是天與海相互交織成的藝術，天的淡藍寬闊、海的深藍厚實，照映了彼此。海鷗們哼著宏亮的音譜，我想，亦是在讚嘆著眼前的美好吧!

美好，卻在這時離開，帶走了一片雲彩。天色逐漸暗沉，就連最後一絲光芒也毫不慰留，被烏雲給遮住了雙眼，漆黑一片。「隆!」「隆!」天空嘶吼著，好像要將天撕裂了一般，閃電也狠心地劃破天際。「不!不!」我雙手緊摀著耳朵，奮力地將眼皮闔起，整個人蜷曲一旁，窩在小帆的角落。心理，祈禱著，不斷地祈禱著這一切能馬上結束，希望甚麼都沒發生過。但是，錯了，無情的巨浪將我吞噬，連同小帆，成了他的美味佳餚，漸漸失去。

「鈴!鈴!」

原來是我睡著了，還好只是個夢啊!鈴聲再次搖響了我，將我拉出黑洞般的世界，要我記得眼前的現在，是溫暖。謝謝你，鈴。

Stopping by Woods on a Snowy Evening 英文/中文

Stopping by Woods on a Snowy Evening

Whose woods these are I think I know.
His house is in the village though;
He will not see me stopping here
To watch his woods fill up with snow.

My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.

He gives his harness bells a shake
To ask if there is some mistake.
The only other sound’s the sweep
Of easy wind and downy flake.

The woods are lovely, dark and deep,
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.

雪晚林邊歇馬

我想我認得這座森林

林主的屋子就在前面小村莊

他卻看不見我於此停歇

凝望白茫茫的雪景

我想牠現在一定深感疑惑

在這不見農莊之處停留

在寒林與冰湖間停下

於最黝黑的黃昏下

牠輕輕搖響韁鈴

似乎在詢問是否該在此佇足

這裡只有微風輕拂雪花

再也沒有其他聲息

樹林很美，也黝黑且深遠

但我能有諾言尚待履行

還要趕多少路才得以安詳

還要趕多少路才得以安詳

The Road Not Taken 英文/中文

The Road Not Taken

Two roads diverged in a yellow wood, 
And sorry I could not travel both,
And be one traveler, long I stood,
 And looked down one as far as I could, 
To where it bent in the undergrowth; 

Then took the other, as just as fair, 
And having perhaps the better claim, 
Because it was grassy and wanted wear; 
Though as for that the passing there 
Had worn them really about the same,

 And both that morning equally lay 
In leaves no step had trodden black. 
Oh, I kept the first for another day! 
Yet knowing how way leads on to way, 
I doubted if I should ever come back. 

I shall be telling this with a sigh
Somewhere ages and ages hence: 
Two roads diverged in a wood, and I— 
I took the one less traveled by, 
And that has made all the difference.

//====translation====

未走之路

黃葉林中延伸出了兩條小徑
遺憾的是，我無法同時涉足
身為旅行者，我久久佇足
盡我所能，遠望其中一條的盡頭
直到它隱沒深處

然後我毅然踏上另一條路
或許這條路更值得我嚮往
因為它荒草叢生，人跡罕至
儘管回頭再看兩路
一樣會足跡遍布

那天早晨，兩條小徑都鋪滿落葉
落葉上都沒有被踩踏的痕跡
哦!我把另一條路留給未來
但我知道人世間阡陌縱橫
我不知道未來能否再回到那李

我將會嘆息與敘說
很久很久以後在某個地方
曾有兩條小路在樹林中分手
我選了一條人跡稀少的旅行
這將會有所不同。
