[問題] inheritance與template結合的作業問題
如版規不合規定請告知，馬上修改
爬了一下文
稍微了解了inheritance跟template的融合
也試著寫了一下，可是出現錯誤訊息
目的是用Inheritance跟template寫出類似stack的資料型態
此stack可以接受多種資料型態(如int float等)
我的寫法是
template <class TL>
class list
{
.
.
.
};
template <class TL>
class stack: TL
{
.
.
.
}
原意是用stack去繼承list
在main裡
int main()
{
list<int> *s1;
stack<int> s;
s1 = &s;
.
.
.
.
}
但compile時出現以下錯誤訊息:
in instantiation of 'stack<int>':
instantiated from here
base type 'int' fails to be struct or class type
In function 'int main()':
's1' undeclared(first use this function)
(Each undeclared identifier is reported only once for each function it
appears in.)
因為是初學template，不知道問題出在哪邊
1. 用了template不是就可將各種型態輸入嗎?
還是我必須在class stack做相關設定呢?
2. s1在main裡一開始不是就宣告了嗎?
為什麼會顯示undeclared?是方法有誤嗎?
如果問了白癡問題請多包涵ˊˋ
我也試了蠻久才硬著頭皮上來問問題的
以上疑問，希望有人能幫忙解答 ，感謝！
