Usage of logical operators in Lua

Usage of logical operators in Lua

This article describes how to use logical operators in Lua. It is the basic knowledge of Lua beginners. For more information, see

The following table lists all logical operators supported by Lua. Assume that variable A holds true, and variable B holds false:

Example

Try the following example to understand the logical operators provided by all Lua programming languages:

The Code is as follows:

A = 5

B = 20

If (a and B)

Then

Print ("Line 1-Condition is true ")

End

If (a or B)

Then

Print ("Line 2-Condition is true ")

End

-- Lets change the value ofa and B

A = 0

B = 10

If (a and B)

Then

Print ("Line 3-Condition is true ")

Else

Print ("Line 3-Condition is not true ")

End

If (not (a and B ))

Then

Print ("Line 4-Condition is true ")

Else

Print ("Line 3-Condition is not true ")

End

When the above program is established and executed, it will produce the following results:

The Code is as follows:

Line 1-Condition is true

Line 2-Condition is true

Line 3-Condition is true

Line 3-Condition is not true
