What is a loop in Lua?

Lua loop is statements that allow the user to execute a specific statement or a group of statements a multiple times. So, a Lua loop has various loop statements such as while loop, for loop, repeats… until loop, nested loops, infinite loop, which have their own looping requirements and the way they are used.

How does the for loop work?

A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.

How do loops work in Lua?

Lua – for Loop

1. The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables.
2. Next, the max/min.
3. After the body of the for loop executes, the flow of the control jumps back up to the increment/decrement statement.
4. The condition is now evaluated again.

How does for work in Lua?

The for loop declares a counter that counts from the first number to the last, and it will call the inner code once for each value it counts. The [] syntax is how you access the members of a Lua table. Lua tables map “keys” to “values”. Your array automatically creates keys of integer type, which increase.

What is loop explain different types of loop?

There are mainly two types of loops: Entry Controlled loops: In this type of loops the test condition is tested before entering the loop body. For Loop and While Loop are entry controlled loops. Exit Controlled Loops: In this type of loops the test condition is tested or evaluated at the end of loop body.

How do you do a while loop in Lua?

Lua – while Loop

1. Syntax. The syntax of a while loop in Lua programming language is as follows − while(condition) do statement(s) end. Here, statement(s) may be a single statement or a block of statements.
2. Flow Diagram. Here, the key point to note is that the while loop might not be executed at all.
3. Example. Live Demo.
