Question

The purpose of this assignment is to reinforce Ada concepts.

• Define a Complex-numbers package includes the following operations:
  • Addition
  • Subtraction
  • Multiplication
  • Division
• A “main program” needs to create one or more complex numbers, perform the various arithmetic operations, and then display results.
• Develop the program in ADA code with several packages. Write a short report that documents all work done, including the overall design, explanation of the implementation, the input data used to run the program, the output of the program. Submit an archive with the source code, the input and output data files, and the document report.

Note: do not include ‘hard-coded’ input data in the Ada source code

Please give positive ratings for my effort. Thanks.

PROGRAM

{

   public static void main(String[] args)
