To define an array, you need an array definition that tells C the name of the array, the type of objects that the array is to contain, the number of dimensions the array has, and the size of each dimension. The C compiler uses array definitions to calculate how much storage to allocate for the array.
The following array definition, for example, tells the C compiler to
allocate memory for a one-dimensional array containing five numbers of type
double, each of which represents the price per share of the stock
involved in one of five stock trades:
*-- Specifies that the array contains floating-point objects | | *-- Specifies that the name of the array is number | | | | *-- Specifies that the array contains five objects | | | v v v double price[5];
