C++ Automation Lab Part IV workbook cover

Inside this volume

Six tools. Four cases each.

Strict Numbers

A report should not silently accept partially parsed numeric text. from_chars reports both an error code and the first unconsumed position. This tool requires one complete base-10 integer per nonempty line, with no surrounding spaces.

Daily Totals

Group a small, deliberately simple record format by key. Each line must contain a day label and a bounded integer separated by whitespace. Validate the full record before modifying totals.

Stats

A useful summary states its empty-input behavior. Track count, minimum, and maximum in one pass. The first value initializes the extremes so negative-only inputs remain correct.

Csv Escape

CSV quoting is necessary when a field contains a comma, quote, or newline. This tool converts each input line into one single-field CSV record. Since getline removes newlines, it handles commas and quotes in the supplied fields.

Html Escape

When text becomes HTML, reserved characters must be escaped. This utility creates safe text content, not safe script, CSS, or arbitrary URL contexts. Output context determines which rules are appropriate.

Reconcile

A reconciliation compares identities rather than positions. Set difference reveals expected items missing from an observed list. A marker separates the two sections. Duplicate identifiers intentionally collapse to one identity.

Read, run, debug, extend.

Each eight-page case includes a lesson, fixture setup, complete source, expected output, a debugging task, verification, an extension, and a handoff record.

A hands-on workbook with writing space. The 200 pages include tracing, planning, and reflection areas. Four cases intentionally revisit each program with different input. Download the sample to see the format before buying.

Your purchase includes the PDF and companion ZIP with six C++ source files, case definitions, expected results, and an optional Python test runner. This is a written workbook. Later volumes build on earlier skills. A C++17 compiler is required.
