A Generic Two-dimensional Array Function

“new and delete with Multidimensional Arrays” on page 156 shows you how to allocate two-dimensional and three-dimensional arrays in free store with operator new and how to release them with operator delete. With operator new, the restriction that all dimensions (except the first) be constant integer expressions is not general enough for most purposes. For this reason, let's design template functions to create and release multidimensional arrays of any size. This approach lets us create a library of routines that you can call when you need to generate multidimensional arrays dynamically.

The following program calls template functions dim2() and free2() to create and release ...
