Step 1: Vector to Array 首先将vector转化为数组,这可以通过使用vector的data()函数来实现,该函数返回指向vector数据的指针。 例如,以下代码将vector转换为一个名为array_pointer的指向整数的指针: vector<int> my_vector; int* array_pointer = my_vector.data(); Step 2: Working with Pointers 转换为指针后...

typedef iterator pointer; vector<bool>::reference 類別類別vector<bool>::reference 是由 類別提供的 vector<bool> Proxy 類別 ,用來模擬 bool&。備註因為C++原生不允許直接參考位,因此需要模擬參考。 vector<bool> 對每個項目只使用一個位元,您可以使用這個 Proxy 類別來參考位元。 不過,參考模擬並未完成,因為某...
data Returns a pointer to the first element in the vector. emplace Inserts an element constructed in place into the vector at a specified position. emplace_back Adds an element constructed in place to the end of the vector. empty Tests if the vector container is empty. end Returns a random...
The elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets to regular pointers to elements. This means that a pointer to an element of a vector may be passed to any function that expects a pointer to an element of an...

查看MSDN,对于erase的返回值是这样描述的:An iterator that designates the first element remaining beyond any elements removed, or a pointer to the end of the vector if no such element exists,于是改代码: for(vector<int>::iterator iter=veci.begin(); iter!=veci.end(); iter++) { if( *iter ...
