Code sample using virtual functions to implement a DataSource class. The class
reads data from some source (command line, random number generator, ...) and
provides them to main(), which computes basic statistics.
The master branch uses a command line interface. You should call the main
program from the command line like:
stats --stdin --prompt="Enter a value please"
stats --random-normal --count=1000000 --mean=6.2 --stdev=0.01(By default, the Makefile produces a program called stats. Your IDE may ignore
that and produce an executable with a different name.)
The prompt-args branch prompts for the command line arguments as the first
line in main(), instead of actually reading the command line. This may be
easier to use with Visual Studio or XCode.
