Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Store "code" in both std::string word and char letters[5]. Change index 1 in each representation to 'O', print both values, then restore "code" using whole-value assignment for word and indexed assignments, including '\0', for letters, and print both restored values.
