Convert Excel VBA script as multicore C++ library

I have an excel sheet that has 531 lines of slow VBA script (4 functions), mostly for-loops. I want whole code converted in to a new C++ library that will be called from VBA. It must be possible to access all 4 functions/functionalities from VBA individually.

Task 1.

- The largest for-loop must be converted to use multiple threads to speed it up. Comment this functionality in the code.

- Number of threads must be autodetected. Comment this functionality in the code.

- The new library must have the same functionalities as the old Excel/VBA. Different number of input rows must be adopted (in old Excel: cells L5 and M5 count the amount of rows). Controlling variables Column K must be included.

- Optimized C++ memory usage - memory must be freed after usage. Comment this functionality in the code.

- Test by changing the input values that the old Excel/VBA produces same results as new Excel/VBA/C++ DLL combination. Provide a PDF of 5 pages, that proves you have conducted this task.

- Full code and complied library must be provided.

Task 2.

- Based on the library created in Task 1, create a C++ program using the DLL with similar capabilities as the excel. The input parameters are read from a CSV file. The C++ library must be the same as used with VBA.

- Full code and complied must be provided.

Skills: Excel, Visual Basic, C++ Programming, Software Architecture
