## Overview

schildtbooklearn is a personal collection of standalone C++ exercises accompanying Herbert Schildt’s textbook, rather than one integrated application. A learner chooses an example, supplies any requested console input, and reads its output. The README describes a 12-module organization and official exercise answers, but the supplied tree contains source files only for modules 1–5 and no answers directory. The graph highlights those topics and representative programs; sampled code supports their individual console behavior, not connections between exercises.

Main entry points: [`module_2/moduleproject_2.3.cpp`](https://github.com/prototype9111/schildtbooklearn/blob/main/module_2/moduleproject_2.3.cpp) (Loan Payment), [`module_3/moduleproject_3.20.cpp`](https://github.com/prototype9111/schildtbooklearn/blob/main/module_3/moduleproject_3.20.cpp) (Lawbook Menu), [`module_1/project_1.2.cpp`](https://github.com/prototype9111/schildtbooklearn/blob/main/module_1/project_1.2.cpp) (Rectangle Area), [`module_1/moduleproject_1.2.cpp`](https://github.com/prototype9111/schildtbooklearn/blob/main/module_1/moduleproject_1.2.cpp) (Feet Conversion)
