with its storage being controlled automatically by the container. Vector items are kept in adjacent storage, which is easy to access and traverse with the help of iterators. Moreover, items are inserted at the end, and it may take some time as an extension ...
Using namespace std::vector::insert(), it will extend the vectors by using to insert the new elements at the correct positions in the vector containers. The elements are being inserted into the container. If the element value is inserted into more in the containers, it automatically increases...

This function contains only one parameter, which is the value parameter as seen above, and is utilized to specify the value that needs to be pushed inside at the back of the specified vector.Consider the following code example:#include <iostream> #include <vector> using namespace std; int ...
C++98 through C++14 performed template argument deduction for function templates. Given a function template liketemplate <typename RanIt> void sort(RanIt first, RanIt last);, you can and should sort astd::vector<int>without explicitly specifying thatRanItisstd::vector<int>::iterator. When the co...
Let’s delve into how to convert a std::vector to an array using the & address-of operator with a distinct example: #include <iostream> #include <vector> int main() { std::vector<int> myVector = {6, 7, 8, 9, 10}; int* myArray = &myVector[0]; std::cout << "Converted Ar...
