How to declare an array using elements in ©++

Question

C++ involves me to love the codes and other programming languages like php web based .

Answer 1

OK it helps a lot

Answer 2

//array of integers

int arr[] = {0, 1, 2};
//array with 3 elements

OR

int arr[3];
//array with 3 elements

You can choose to give it values when you define it (example 1) or show how big it will be inside the square brackets (example 2). You can also do both, but at least one is required.
