Sudoku (C)

A generalized Sudoku solver written in C. Built as part of my Master’s in Cryptology & Computer Security at the University of Bordeaux, it was also my first time learning C.

Features

• Solves classic 9×9 and larger N×N boards (where N is a perfect square, e.g., 4, 9, 16, 25, 36, 64).
• Reads a puzzle from via file redirection and prints the solved grid (all solutions or only one), or reports failure.
• Can also generate solvable grids, with unique or multiple solutions.
• Minimal dependencies: a C compiler and make.
