What is a foreach loop in C++?

Can you explain what a foreach loop is in C++?

Sure! A foreach loop in C++ is used to iterate over elements in a collection, like arrays or vectors.

How does it differ from a regular for loop?

A foreach loop simplifies the syntax and automatically handles the iteration, making the code cleaner and easier to read.

Can you provide an example of a foreach loop?

Certainly! 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 foreach loops?

Yes, foreach loops cannot modify the elements of the collection directly. If you need to modify elements, a regular for loop is better.
