Implement find_max to write the greatest array value into out. Return 1 on success and 0 when the array is empty, the pointer is null, or out is null.
{ -4, 12, 0 }, 3success, 12Write down the input contract and the failure cases before coding.
Ready to run the file open above against 2 tests.
The first element is only safe to use after the empty case has been rejected. Computing into a local maximum and assigning out at the end means callers never receive a partial or invented result when the input contract fails.
your-solution.c.solution.c only after a real attempt.This beginner C exercise focuses on Array traversal, Output parameters, Preconditions. Its requirements define the exact behavior to implement before you write code.
Start with the displayed example input and expected output, then test a boundary case suggested by the requirements. Open your-solution.c and select Run code. The browser uses the same safe C subset as the C course, including a test harness for exercise functions.
Attempt Find the maximum safely first. Then open the read-only solution file to compare the contract, edge-case handling, and implementation choices—not simply to copy the final code.
