# Ada Cheatsheet

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.

## Unique Features
- High-level, strongly typed programming language
- Used in safety-critical systems, such as aerospace and defense
- Strong typing, modularity, and support for concurrency

## Variables

-- declaring a variable

variable_name : data_type := value;

-- dynamic typing

variable_name : any := "string";

variable_name : any := 123;

## Functions

-- defining a function

function function_name(parameter1 : data_type; parameter2 : data_type) return return_type is

-- function body

begin

return value;

end function;

-- calling a function

variable_name := function_name(argument1, argument2);

## Loops

-- for loop

for variable_name in range loop

-- loop body

end loop;

-- while loop

while condition loop

-- loop body

end loop;

-- loop through an array

for i in array_name'range loop

-- loop body

end loop;

## Conditionals

-- if statement

if condition then

-- if body

elsif condition then

-- else if body

else

-- else body

end if;

-- ternary operator

variable_name := (condition) ? true_body : false_body;

## File Manipulation

-- reading from a file

file_name : file_type;

line : string;

begin

file_name := file_type("filename");

while not end_of_file(file_name) loop

readline(file_name, line);

-- process line

end loop;

close(file_name);

end;

-- writing to a file

file_name : file_type;

begin

file_name := file_type("filename", mode => out_file);

put(file_name, "content");

close(file_name);

end;
