## Overview

A C++ console application guides the user through selecting wheat variety, soil, fertilizer, region, and seasonal weather, then calculates and displays an estimated yield. `main.cpp` is the interactive entry point; it loads the JSON-backed options and passes the selections to the predictor. The predictor applies the documented agronomic factors, variety sensitivity and resistance, then clamps the result to the variety’s yield bounds. The README documents these capabilities; the sampled implementation supports the loading, selection, calculation, and display relationships shown here.

Main entry points: [`src/ConfigLoader.cpp`](https://github.com/drotyk/wheat-yield-predictor/blob/main/src/ConfigLoader.cpp) (Config loader), [`src/WheatYieldPredictor.cpp`](https://github.com/drotyk/wheat-yield-predictor/blob/main/src/WheatYieldPredictor.cpp) (Yield predictor), [`main.cpp`](https://github.com/drotyk/wheat-yield-predictor/blob/main/main.cpp) (Interactive menu), [`cls/WheatVariety.h`](https://github.com/drotyk/wheat-yield-predictor/blob/main/cls/WheatVariety.h) (Wheat variety)
