15-minute session: read for 3 minutes, trace for 3, experiment for 7, and complete the check for 2. Spend longer whenever you need.
A decision chooses which statements run. The policy here is “ready at 80 or higher.” Trace 85, 79, 80, and 81 before running each case. The comparison includes 80. A program that prints the right answer for 85 may still be wrong at the boundary. Add a separate check rejecting scores below 0 or above 100; rejection and needing practice mean different things.
std::cout writes output. std::vector 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.
#include <iostream>
#include <vector>
#include <string>
#include <cassert>
int main() {
int score = 85;
std::cout << (score >= 80 ? "Ready" : "Practice") << "\n";
}
Expected result: Ready
Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.
