This cheatsheet provides a brief overview of Ada’s unique features and syntax, including code blocks for variables, functions, loops, conditionals, file manipulation, and more.
Ada is a high-level, strongly typed programming language that is used in safety-critical systems, such as aerospace and defense. It is known for its strong typing, modularity, and support for concurrency.
This cheatsheet is designed to serve as a quick reference guide for Ada developers of all levels. It includes examples of common syntax and programming constructs, as well as a list of resources for further learning.
