Join Bill Weinman for an in-depth discussion in this video Command line interface, part of Code Clinic: C++.
- Like most of my C++ solutions in this series,…my nQueen solution uses a command line interface.…Let's take a look at how this works.…Here I have all the files for this particular solution.…I'm just going to type "make"…and that will run the Make file…and compile this all into one executable.…Then I can type dot slash nQueens.…I'm on a Unix sytem here.…It's actually Red Hat Linux,…and this is one of my servers out at rack space.…If I just type nQueens by itself,…it will default to solving for eight queens…on an eight by eight board.…
It finds 92 solutions, which we know…is the correct answer.…I can specify that I want to solve for five queens…on a five by five board…by simply typing a five here,…and I get 10 solution.…Or I can solve for 12, if I want to,…and I'll see there's 14,200 solutions.…And these are the right answers.…If I want to, I can get a list of the solutions…by typing dash dash short.…I can use any number of dashes.…I can use one dash or three dashes, it doesn't matter.…
We'll see how I do that in the code later.…
Bill introduces challenges and provides an overview of his solutions in C++. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
Visit other courses in the series to see how to solve the exact same challenges in languages like C#, Java, PHP, Python, and Ruby.
