Sanitizers detect common errors reducing security vulnerabilities. Warning flags promote best practices and code quality. By incorporating these tools, developers can enhance the security, reliability, and maintainability of their C++ codebases. Since sanitizers run at runtime, it is essential to have automated tests in the codebase. @@ -49,8 +52,66 @@ cp initcpp.sh ~/.local/bin/initcpp ``` ### Usage -To create a new C++ project, run the script with the project name as an argument.
