end

This example demonstrates a simple Lua function that calculates the sum of two numbers. The function takes two parameters, “a” and “b”, and returns their sum. In Lua, functions are defined using the “function” keyword followed by the function name and a pair of parentheses. The body of the function is enclosed in a block that is indented. This example highlights Lua’s clear and concise syntax.

Example 2:

local fruits = {“apple”, “banana”, “orange”}

for i, fruit in ipairs(fruits) do

print(“I love ” .. fruit)

end

In this example, an array called “fruits” is defined, containing three elements: “apple”, “banana”, and “orange. The “for” loop is used to iterate over each element of the array. The “ipairs” function is used to retrieve the index and value of each element. Within the loop, the Lua “print” function is used to output a message for each fruit. This example demonstrates Lua’s support for data manipulation and looping constructs.

Example 3:

local function factorial(n)

if n == 0 then

return 1

else

return n * factorial(n-1)

end

end

This example showcases a Lua function called “factorial” that calculates the factorial of a given number. The function uses recursion to calculate the factorial by multiplying the number with the factorial of its predecessor. This example demonstrates Lua’s support for recursive functions and showcases its flexibility in solving complex mathematical problems.

These examples provide a glimpse into the syntax and capabilities of Lua. Whether it’s simple arithmetic calculations, data manipulation, or solving complex problems, Lua offers a versatile and powerful toolset for developers to create a wide range of applications.
