The use of While loop statements in Lua

This article focuses on the use of while loop statements in Lua, the basics of Lua's introductory learning, and the need for friends to refer to

A while loop statement in the LUA programming language that repeats the target statement whenever a given condition is true.

Grammar

The syntax for a while loop in the LUA programming language is:

The code is as follows:

while (condition)

Todo

Statement (s)

End

Here, the declaration (S) can be a single statement or block of statements. The condition can be any expression, and it is really any value that is not 0. Loop iterations when the condition is true.

When the condition is false, the program control enters the row immediately after the loop.

Flow chart:

Here, the key point in the while loop is that the loop may not run forever. When the condition test results are false, the loop body is skipped, and the first statement after the loop is executed.

For example:

The code is as follows:

a=10

while (a < 20)

Todo

Print ("Value of A:", a)

A = A+1

End

When the above code is compiled and executed, it produces the following results:

The code is as follows:

Value of A:10

Value of A:11

Value of A:12

Value of A:13

Value of A:14

Value of A:15

Value of A:16

Value of A:17

Value of A:18

Value of a:19
