Demo sourcecode of application for my client - C++

Hi freelancers, I am currently working on project which will allow me to provide my employer with demo sourcecode of application that needs to emulate/simulate a basic store management tool - we are looking for freelancers who are fluent in C++ and can provide us with some demo CLI application, we are going to improve this and in upcoming weeks we will try to launch z fully functional code with GUI elements. But for time being, we are just looking for simple sample in C++ - nothing really major. All requirements will be delivered once you drop me a message - I do understand freelancer is gathering people from all around the world, but I need this really quick - therefore first freelancers will be considered for this job for 'test app'.
