C++ in Ubuntu Complie with g++ -std=c++11 and fltk-config
Command Line Interfaces (CLI) can be very productive for technical people, but are not acceptable to normal users. They prefer rich, graphical interfaces, and our job as professional software developers is to provide interfaces that delight our users. But not this week. Instead, we'll start by implementing a literal replacement of the console menus and inputs with pre-defined FLTK dialogs, mainly fl_input (for commands and data prompts) and fl_message (for reports). Below are some examples using a library model.
Requirements
Port your solution (or the suggested solution provided with this assignment, if you prefer), to an all-GUI, dialog-only implementation. For this sprint, you need use only the pre-defined FLTK dialogs discussed in class and documented at http://www.fltk.org/doc-1.3/group__group__comdlg.html.
(You will receive partial credit if you only implement a portion of the requirements. You will be graded on the extent to which you cover the requirements and the quality of your code. For FLTK programs only, you are permitted but not required to put all of your code into a single source code file. Use Scrum to manage this second sprint. If you don't understand the intent of a requirement, feel free to ask although reasonable assumptions without asking are also fine if you've used a library.)
Need to modify the code in any fashion necessary to accomplish the pictures above using FLTK.
