Function Declaration
Introduction
Functions in AVAP™ are reusable blocks of code that perform a specific task. Just like in Python, functions in AVAP™ allow for code modularization, improved readability, easier maintenance, and code reuse.

Function Construction
In AVAP™, similar to Python, functions are defined using the keyword function , followed by the function name and its parameters in parentheses. The function definition ends with a {, followed by the block of code that forms the function body, and closed by }.

Defining a function in AVAP™
function greet(name){
            return("Hello, " + name + "!")
          }
            
Calling the function
message = greet("World")
            addResult(message)
Output
Hello, World!
Technical Features
Parameters: Functions can accept zero or more parameters that are used as inputs to the function.
Return Values: Functions can return a value using the return keyword.
Scope: Functions in AVAP™ have their own scope, meaning that variables defined within a function are only visible within that function unless declared as global variables.
Code Reusability: Functions allow for encapsulating and reusing blocks of code that perform specific tasks.
Practical Example
Below is a practical example illustrating the definition and invocation of a function in AVAP™:

Definition of a Function to Calculate the Area of a Circle
function calculate_circle_area(radius){
              return(3.14 * radius ** 2)
          }
Calling the Function
circle_radius = 5
              area = calculate_circle_area(circle_radius)
              result = "The area of the circle is: %s" % area
              addResult(result)
          
Output:
The area of the circle is: 78.5
Conclusions
Functions are a fundamental part of programming in AVAP™, allowing for effective organization and modularization of code. By understanding how to define, construct, and call functions in AVAP™, developers can write clearer, more concise, and maintainable code, facilitating the development and management of applications.
