Let’s do some more with our statistics package. We already have a static library that accumulates sums toward a linear regression. This library has some limitations, however.
The statistics are limited. For instance, because the library doesn’t keep individual data points, we can’t calculate standard deviations.
The header file is a separate entity from the library. By the standard means of distributing libraries and headers, users of our library will have to separate the header and the library into different directories, such as /
usr/local/lib and /
usr/local/include, and specify the additional directories at build time, an accident-prone process. One file or the other can get lost, deleted, or miss a ...
