A one-dimensional array is a collection of places where objects are stored and retrieved using an integer index. Each object in an array is called an element of that array. In C++, the first element is indexed by zero; hence, C++ is said to have zero-based arrays.
The following, for example, is a one-dimensional array with integer elements:
0 1 2 3 4 <-- Index *-----*-----*-----*-----*-----* | 57 | 72 | 94 | 22 | 35 | *-----*-----*-----*-----*-----*
