This is the most naïve approach to initialize a vector. Firstly, we just define an empty vector. At that point, it has no idea about how many elements it’s going to have. Then by usingpush_back()function we can simply keep adding elements at the back as per requirement. Example Be...
What is a vector? Vectors are similar to arrays but their size can grow dynamically. Vectors can expand or shrink dynamically during the insertion and deletion of elements. It stores the elements in contiguous memory locations. Hence the size of the vector changes during the execution of the pr...
