Define a vector of pointers called pvector Sep 10, 2017 at 12:59pm Frank14(93) Hello, The following is the exercise no. 15. https://s2.postimg.org/wyjwt43ll/image.png Just like many other exercises it's not com
Hey guys, If I have a Vector of pointers, how can I iterate through that vector, to access the name function of each object in the vector? There seems to be a problem with my implementation, the output returns only random symbols. Implementation of the name() function in Drug.cpp: 12...
1.Cpp中的vector(可变长的动态数组) vector是顺序容器的一种。vector是可变长的动态数组,支持随机访问迭代器,所有STL算法都能对vector进行操作。要使用vector,需要包含头文件vector。在vector容器中,根据下标随机访问某个元素的时间是常数,在尾部添加一个元素的时间大多数情况下也是常数,总体来说速度很快。在中间插入或...

It operates on raw pointers (char or char16_t) for maximum efficiency. std::string input = "abc"; const char* result = simdutf::find(input.data(), input.data() + input.size(), 'c'); // result should point at the letter 'c' The simdutf::find interface is straightforward and ...

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...
