Curve Fitting Interpolation Program

Purpose

Fitting a curve to a set of data points and interpolating between them is foundational numerical work, but it's easy to get wrong when the coefficients are computed by hand and never shown clearly. This program set out to fit polynomial curves to data and interpolate between points, laying out every computed coefficient so the result can be checked step by step.

Description

We built a program that fits polynomial curves, up to the fourth degree, to user-supplied data points and interpolates across them. It reads test data from file, computes the coefficient set for each fitted segment, and prints clean, formatted tables from the highest-order term down to the constant, so the math is transparent at every step. It ships as a compiled Windows program, a small, self-contained piece of numerical engineering.
