## Overview

ProjetosC is a collection of standalone C study exercises, not one integrated application. The user workflow is to choose and compile an individual program, provide input where it prompts, and observe its calculated or transformed output. Directory themes cover matrices, strings, pointers, and general logic, with additional random exercises and exam practice. `utils.c` provides reusable string operations, but the supplied source evidence does not show exercises calling it; connections between the utility and exercises are therefore omitted.

Main entry points: [`Prova/exercicio2.c`](https://github.com/bpoltosi/projetosc/blob/main/Prova/exercicio2.c) (Matrix submatrix), [`ListaMatrizes1/matriz3v2.c`](https://github.com/bpoltosi/projetosc/blob/main/ListaMatrizes1/matriz3v2.c) (Row/column sums), [`ListaMatrizes1/matriz9.c`](https://github.com/bpoltosi/projetosc/blob/main/ListaMatrizes1/matriz9.c) (Element classification), [`ListaStrings/Exercicio6.c`](https://github.com/bpoltosi/projetosc/blob/main/ListaStrings/Exercicio6.c) (Interleave strings)
