Assignment 1 · Course Record Card — Variables, I/O, Arithmetic

Modules 1–2 (L01–L04) · 40 marks · due end of Week 3 Outcomes: CLO-1, CLO-2 (PF-1.x, PF-2.x)

A department office prints student record cards. You will produce one card from keyboard input, with correctly typed and formatted numbers.

Requirements

1. Read, in this order: student name (single word), age (int), lab grade, midterm grade, final grade (doubles, 0–100).
2. Print a card exactly in this shape (example values Ayesha 20 88 79 91):

=== COURSE RECORD ===
name   : Ayesha
age    : 20
lab    : 88.00
midterm: 79.00
final  : 91.00
average: 86.00 (weighted: lab 25% / midterm 35% / final 40%)

1. The weighted average must use the stated percentages and print with exactly 2 decimals (std::fixed, std::setprecision(2)).
2. If any read fails (EOF or non-numeric), print bad input and exit with code 1.
3. Grades outside 0–100: print bad input and exit with code 1 (no card).

Constraints

• Use int for age only; grades are double.
• The weighted average must be computed in one expression with a static_cast<double> somewhere it is needed.
• No functions beyond main are required yet (decomposition is graded from A3 onward).

Sample runs

input:  Ayesha 20 88 79 91
output: (card above; average: 86.00)

Check: 88·0.25 + 79·0.35 + 91·0.40 = 22 + 27.65 + 36.4 = 86.05 → the sample card should print 86.05; if your program prints 86.00 you have an integer-division or precedence defect.

Deliverables

1. record_card.cpp — compiles with the course contract, zero warnings.
2. test_table.md — at least: two typical runs, one boundary (grade 0 and 100), one invalid grade, one failed read (EOF). Pre-compute expected values before running (testing.md rubric).
3. postmortem.md — one real defect you hit: symptom → hypothesis → test → fix (explanation.md rubric, 10 of the 40 marks).

Submission

Zip record_card.cpp, test_table.md, postmortem.md. Naming per ../../labs/resources/submission_template.md. Late policy per syllabus.
