Program Notes

First, the program in Listing 4.1 creates a three-element array called yams. Because yams has three elements, the elements are numbered from 0 through 2, and arrayone.cpp uses index values of 0 through 2 to assign values to the three individual elements. Each individual yam element is an int with all the rights and privileges of an int type, so arrayone.cpp can, and does, assign values to elements, add elements, multiply elements, and display elements.

The program uses the long way to assign values to the yam elements. C++ also lets you initialize array elements within the declaration statement. Listing 4.1 uses this shortcut to assign values to the yamcosts array:

int yamcosts[3] = {20, 30, 5};

It simply provides a comma-separated ...
