Range based for loops were introduced in C++11. Watch different ways to iterate or loop over a Vector in C++. In C++, vector class provides two different functions, that returns the iterator of start & end of vector, vector::begin () –> Returns an iterator that points to the start of vector, vector::end () –> Returns an iterator that points to the end of vector. We can also use the iterators to loop over all elements of a vector. Do i need to declare another iterator to traverse the rows and another one to traverse each elements? How can I use an iterator for a 2D vector?Īncient Dragon’s example will work for the first elemend of the 2D vector, and you’ll probably have to nest it to go through all the rows of the 2D vector. So it keeps repeating a lphaV, alphaV, alphaV, etc. When I try to use a nested For loop to process this vector I run into problems whereby the rows of the vector will not iterate, that is to say they remain at index 0. Let’s see how we can use these range based for loops to iterate over a vector of integers and print each element while iteration, Why are the rows of a vector not iterating?

How to iterate over all elements of a vector? You have to implement these iterator classes yourself, which is not necessarily a trivial thing to do.

Row iterators would move “up” and “down” the matrix, whereas column iterators would move “left” and “right”. What kind of iterator do you need for a 2D vector?Ī 2D vector is a matrix, and so you’d need two iterator types: a row iterator and a column iterator. The code creates a 2D vector by using the push_back() function and then displays the matrix. Below example demonstrates the insertion operation in a vector of vectors.

Check if the element at each position is divisible by 2, if yes, remove the element and decrement iterator.Įlements can be inserted into a vector using the push_back() function of C++ STL.

Run a loop till the size of the vector.

Clear() function is used to remove all the elements of the vector container, thus making it size 0….Algorithm
