題目描述

設(shè)計(jì)一個(gè)時(shí)間類Time，要求：
1、包含時(shí)(hour)，分(minute)，秒(second)私有數(shù)據(jù)成員；
2、包含構(gòu)造函數(shù)，重載關(guān)于一時(shí)間加上另一時(shí)間的加法運(yùn)算符"+"、重載輸出運(yùn)算符"<<"、重載輸入運(yùn)算符">>"。
要求，定義完Time類后，main函數(shù)中聲明對(duì)象time1,time2,time3，然后實(shí)現(xiàn)

cin>>time1>>time2; time3=time1+time2; cout<<time3<<endl;

輸入描述

輸入時(shí)間一、時(shí)間二，注意：在main函數(shù)中必須用cin>>time1>>time2實(shí)現(xiàn)輸入

輸出描述

輸出兩個(gè)時(shí)間相加的結(jié)果，注意，在main函數(shù)中必須用cout<<time3<<endl實(shí)現(xiàn)輸出

輸入樣例

12:30:59 2:30:01
