What is a range-based for loop in C++?

Can you explain what a range-based for loop is in C++?

Sure! A range-based for loop in C++ allows you to iterate over elements in a container, like arrays or vectors, without needing an index.

How does it differ from a traditional for loop?

In a traditional for loop, you manually manage the index and the loop's bounds. The range-based for loop simplifies this by automatically iterating through each element.

Can you give me an example of how to use it?

Of course! Here's a simple example:

std::vector<int> numbers = {1, 2, 3, 4, 5};
for (int num : numbers) {
    std::cout << num << ' ';
}

This will print each number in the vector.

Are there any limitations to using range-based for loops?

Yes, you can't modify the container while iterating through it, and it doesn't provide access to the index of the elements.
