Spend longer whenever you need.</p><p>A program is a set of instructions. Read the example from its entry point to the output statement. Text in quotes is data; the output operation is an instruction. Predict the printed line before running. Change only the message, run again, then remove one required punctuation mark and read the first error. Restore the working source.</p><p><code>std::cout</code> writes output. <code>std::vector</code> manages a growing sequence and releases its storage when its lifetime ends. The lab selects C++17; an example that compiles under a different standard needs its settings recorded.</p><pre><code class="language-cpp">#include <iostream>
