How do I initialize an array in C++?

How do I initialize an array in C++?

You can initialize an array in C++ by specifying the size and using curly braces. For example: int arr[5] = {1, 2, 3, 4, 5};.

What if I want to initialize an array without specifying the size?

You can do that by using an initializer list. For example: int arr[] = {1, 2, 3, 4, 5}; will automatically size the array.

Can I initialize a multidimensional array?

Yes, you can initialize a multidimensional array like this: int arr[2][3] = {{1, 2, 3}, {4, 5, 6}};.

What happens if I don't initialize the array?

If you don't initialize an array, its elements will contain garbage values unless it's a static or global array, which will be initialized to zero.
