[問題] compile error

[meanid (meanid)]

有幾個看不懂的error麻煩強者帮我解答一下．．．

第一個:

cirMgr.cpp:234: error: ‘class __gnu_cxx::__normal_iterator<CirPiGate**,
std::vector<CirPiGate*, std::allocator<CirPiGate*> > >’ has no member named ‘
getId’


code:

vector<CirPiGate*>::iterator its;
its = _pi.begin();
for(; its< _pi.end(); its++)
   if(its.getId() == id)
             .
             .
             .

_pi是一個我用來存CirPiGate*的vector

CirPiGate 是一個計承 CirGate 的  class

以上四行code是在一個switch case裡面的

我檢查過了裡面有getId 這個 member function(在CirGate裡面，非virtual)



第二個:


cirMgr.cpp:303: error: switch quantity not an integer


code:

switch(ilo.c_str()){
           .
           .
           .

ilo是一個只有一個字的string

想把它轉成char來判斷

不知道這樣轉可不可以??




麻煩各位了QQ

推 jjjj222:(*its).getId()
推 jjjj222:or (*its)->getId()? since the data in vector is an ptr
推 jjjj222:switch can only accept "int", and x.c_str() is char*
推 jjjj222:I think you should use "ilo[0]"
→ meanid:got it!! thx!!
