bug: some format-overflow warnings

[RodrigoDornelles]

estou trabalhando na #2, e acabei percebendo que existe alguns warnings, posso também corrigilos em mandar em PR a parte. alias qual o estilo de identação seguido? seria GNU?

@rafael2k na real, posso fazer um checkup no projeto, como fazer CI/CD, mover buffers da stack para global, colocar linter, teste de identação, teste de memoria. colocar .gitignore e explicar mais coisas na README.md
