📝 Walkthrough

Walkthrough

This PR adds a missing header dependency to the MPS parser and improves robustness in the MILP example code by properly gating solution output on primal solution availability and adding explicit out-of-memory error handling.

Changes

Parser and Example Code Fixes

Layer / File(s)	Summary
Utility header dependency cpp/src/io/mps_parser.cpp	Added #include <utility> to the file's includes.
MILP example solution printing and memory handling docs/cuopt/source/cuopt-c/lp-qp-milp/examples/milp_mps_example.c	Objective value and solution-values allocation/retrieval moved under has_primal_solution conditional; malloc size cast to size_t; explicit CUOPT_OUT_OF_MEMORY status assignment added on allocation failure; solution variable printing indentation adjusted to match updated control flow.
