The std::vector function is generally known as a dynamic array. It automatically manages the dynamic memory internally and keeps the elements stored contiguously similar to a C-style array. The latter feature makes it possible to access elements in constant time. On the other hand, the std::...
vector拥有一段连续的内存空间,能很好的支持随机存取, 因此vector<int>::iterator支持“+”,“+=”,“<”等操作符。 list的内存空间可以是不连续,它不支持随机访问, 因此list<int>::iterator则不支持“+”、“+=”、“<”等 vector<int>::iterator和list<int>::iterator都重载了“++”运算符。 总之,如果...
vector<类型> a名称(初始化个数); 例如: vector<int> a(n);//初始化n个元素的向量 vector<int> a(n,x);//初始化n个元素的向量,每个元素是x vector<int> a = {1,2,3,4,5};//支持数组声明的方法,自动创建 //二维 vector<vector<int>> matrix(n,vector<int>(m));//m*n的矩阵 其他的构...
template<class elemType> inline elemType* begin(const vector<elemType>& vec) { return vec.empty() ? 0: (elemType*)&vec[0]} 类似地,可以把“取最后一个元素地址”的操作包装成函数end(); 这样,find(begin(vec), end(vec), search_object)就能对所有的vector都适用了。 find()适用于list吗? find(...
