Accessing array elements

Each element of an array is accessed via its base name and an index into the array. An index is also known as a subscript. Each element is accessed using the following form:

arrayName[ index ]

Here, index is a value between 0 and the (array size minus 1). We can access any element of an array using this form. Just as with defining an array, the index may be a literal value, a variable, the result of a function call, or the result of an expression, as follows:

float anArray[10] = {2.0};

int   counter = 9;

float aFloat  = 0.0; 

aFloat = anArray[ 9 ];             // Access last element.

aFloat = anArray[ counter ];       // Access last element 

                             ...
