How do I initialize arrays in C++?

In C++, you can initialize arrays in several ways. For example, you can use curly braces: int arr[] = {1, 2, 3};.

What if I want to initialize an array with a specific size?

You can specify the size like this: int arr[5]; and then initialize it later, or use: int arr[5] = {0}; to set all elements to zero.

Can I initialize an array with all elements the same value?

Yes, you can use a loop to set all elements to the same value, or use: int arr[5] = {value, value, value, value, value};.

Are there any differences between static and dynamic arrays?

Yes, static arrays have a fixed size determined at compile time, while dynamic arrays can change size at runtime using pointers and new.
