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

1F：推 jjjj222:(*its).getId() 12/21 21:14
2F：推 jjjj222:or (*its)->getId()? since the data in vector is an ptr 12/21 21:15
3F：推 jjjj222:switch can only accept "int", and x.c_str() is char* 12/21 21:17
4F：推 jjjj222:I think you should use "ilo[0]" 12/21 21:18
5F：→ meanid:got it!! thx!! 12/21 21:37
