An ARRAY is a sequence of values of a given data type, arranged contiguously in memory. Arrays are declared by following the identifier with an integer constant enclosed in [] brackets. To declare an array of 10 floats requires:
float f_array[10];
Individual ELEMENTS of an array are accessed using the index in brackets. Indexing begins at 0, so in the above example, elements f_array[0] through f_array[9] are allocated appropriately, but f_array[10] should not be accessed.
f_array[5] = 100.;
Multi-dimensional arrays are declared using the following syntax:
float f_array[10] [10];
This declares a 10 by 10 array. The indexing begins with 0 for both rows and columns.
