C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing the elements equals to the val (value to ...
In C++, Vectors are called dynamic arrays that can automatically resize themselves when an item is inserted or removed, 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. Mo...

The problem is that you're adding things to the vector so it ends up with more elements than were in themyarrarray that you initialized it with. If you want to copy the vector back into the array, you'll need to size it down: ...
There’s no universal way of calculating the size of C-style arrays without worrying about many edge cases, and that’s why thestd::vectorclass exists. Usearray.size()Function to Calculate Array Length in C++ In C++, thearray.size()functionallows us to determine the size of an array at...
