This work is both an introduction to Hoare logic and a demo illustrating Coq nice features. It formalizes the generation of PO (proof obligations) in a Hoare logic for a very basic imperative programming language. It proves the soundness and the completeness of the PO generation both in partial and total correctness. At last, it examplifies on a very simple example (a GCD computation) how the PO generation can simplify concrete proofs. Coq is indeed able to compute PO on concrete programs: we say here that the generation of proof obligations is reflected in Coq. Technically, the PO generation is here performed through Dijkstra's weakest-precondition calculus.

Dry install with the current Coq version:

- Command
`opam install -y --show-action coq-hoare-tut.8.11.1 coq.8.13.0`

- Return code

- Output
[NOTE] Package coq is already installed (current version is 8.13.0). The following dependencies couldn't be met: - coq-hoare-tut -> coq < 8.13~ -> ocaml < 4.10 base of this switch (use `--unlock-base' to force) Your request can't be satisfied: - No available version of coq satisfies the constraints No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

- Command
`opam remove -y coq; opam install -y --show-action --unlock-base coq-hoare-tut.8.11.1`
