How do I pass arrays to functions in C++?

How do I pass arrays to functions in C++?

In C++, you can pass arrays to functions by using the array name without brackets. For example, void myFunction(int arr[]).

What happens if I pass an array with a different size?

When you pass an array to a function, it decays to a pointer, so the function won't know the size of the array. You should pass the size as an additional parameter.

Can I pass a multidimensional array?

Yes, you can pass multidimensional arrays by specifying the sizes of all dimensions except the first. For example, void myFunction(int arr[][3]) for a 2D array.

Is there a way to pass an array by reference?

Yes, you can pass an array by reference using the syntax void myFunction(int (&arr)[size]), which allows you to modify the original array.
