Arrays revealed (1 d mainly) in cpp

First, there are only one-dimensional arrays in C or C++. The number of elements is put between brackets:

Expand|Select|Wrap|Line Numbers

1. int array[5];
2.  

That is an array of 5 elements each of which is an int.

Expand|Select|Wrap|Line Numbers

1. int array[];
2.  

won't compile. You need to declare the number of elements.
