若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorFindAndErase.cpp ...

CAutoPtrArray 和CAutoPtrList 類別衍生自 CAutoPtrElementTraits。 如果建置需要向量 new 和 delete 運算符的智慧型手機集合,請改用 CAutoVectorPtrElementTraits。 繼承階層架構 CDefaultCompareTraits CDefaultHashTraits CElementTraitsBase CDefaultElementTraits CAutoPtrElementTraits 需求 標頭: atlcoll.h CAuto...
if (v == NULL) { // Vector不能是NULL return; } if (v->size == v->capacity) { // 容量不足,扩容 vector_rsize(v); } v->data[v->size] = val; v->size++; } // 向数组的前面插入一个元素 void vector_push_front(MY_VECTOR *v, Element val) { ...
CAutoVectorPtr與CAutoPtr類似,唯一的差異在於CAutoVectorPtr使用vector new[]和vector delete[]來配置和釋放記憶體,而不是C++new和delete運算符。 如果需要 的集合類別CAutoVectorPtr,請參閱CAutoVectorPtrElementTraits。 如需使用智慧型指標類別的範例,請參閱CAutoPtr。
头部进一步定义了这些(和一些其他)类型的最小值和最大值的宏:例如,INT_FAST_8_MIN和INT_FAST_8_MAX代表std::int_fast8_t。不过,获得这些值的标准 C++ 方法是使用下面讨论的<limits>工具。 算术类型属性<limits> std::numeric_limits<T>模板类提供了大量的静态函数和常量来获取数字类型T的属性。它专门用于所...
