今天為大家帶來一篇關於大整數類的文章，簡單的寫了一下關於大整數類的**，類說白了就是在struct結構體裡面寫下只有它自己能呼叫的函式。不多說了 ，寫了乙個小時。這裡沒有寫關於取餘，除法，乘方的，還有正負沒有打標記，有興趣的讀者可以自己去改。

bignum operator + (bignum b)
for(int i=minn;iif(maxx==b.v.size())
t.push_back(b.v[i]);
else
t.push_back(v[i]);
}for (int i=minn;i1;i++)
if (t[i]>9)
if (t[maxx-1]>9)
bignum tep;
tep.v=t;
return tep;
}//只允許用大的減去小的，可以先判斷一下再加減
//bool positive表示正負 這裡沒有 讀者可依據實際情況自行修改
bignum operator - (bignum b) const
