我试图学习像迭代器一样编写stl,因为我写了一个简单的循环数组并在其中添加了一个迭代器.请查看代码底部以查看问题.
template<typename T, int N>
class RingQueue{
T * _marray;
int _mbegin;
int _msize;
public:
RingQueue(){
_marray = new T[N];
_mbegin = 0;
_msize= 0;
}
void push_back(const T& val){
if(_msize!=N){
_marray[(_mbegin+_msize)%N] = val;
_msize++;
}
else
throw "Queue Full";
}
T pop_front(){
if(_msize!=0){
T&val = _marray[_mbegin];
_mbegin = (_mbegin+1)%N;
_msize--;
return val;
}
else
throw "Queue Empty";
}
class iterator{
RingQueue<T,N>* _container;
int _idx;
public:
iterator(RingQueue<T,N>* container,int idx):_container(container){
_idx = idx;
}
bool operator==(iterator &rhs){
return (this->_container==rhs._container && this->_idx …Run Code Online (Sandbox Code Playgroud)
