How does a range-based for loop work in C++11 and above?
- It works only on arrays and not on containers.
- It iterates over elements using indices.
- It allows iterating over all elements in a container or array directly.
- It requires manual initialization of iterators.
In C++11 and newer versions, the range-based for loop provides a more readable syntax to iterate over all elements of a container or an array. The loop automatically gets the begin and end iterators of the range and iterates over each element without needing manual indexing.
