Question

Multiplication Table Teaching and Testing Programming Project Please read this entire document carefully and abide by the requirements exactly. Your project mark will depend on this General description In this project, you are required to write an Intel x86 16-bit assembly language program that will teach and test youngsters the simple 1-12 multiplication table. The program shall be divided into two parts one part is to show examples through which youngsters can learn the basics of the multiplication table The other part is used to test and report on how good the user has learned the multiplication table This project is to be done by a team of two students. One student will be responsible for the teaching part, while the second student is responsible for the testing and reporting part. It is expected that each student will use his preferred approach to accomplish the task. You are free to choose any method you find suitable. You can use graphics or text mode to accomplish the tasks. It is essential that you plan your work carefully before starting the code for a successful project. You will work in teams of two students. However, teamwork here does not mean that everyone is involved with the same work. Each team once formed, should have an initial meeting where they study the project requirements carefully, then divide the necessary work into tasks and subtasks and thern assign each to a member of the team who will be the sole responsible person for the assigned tasks. This Deliverables 1 A fully working properly commented .asm file performing all the above required operations written in x86 16 bit assembly language and running on the emu8086 emulator
