Volume that wants to use a lot of logical operators in if statements

Introduction

I will summarize how to use logical operators when you want to overlap conditions in if statements that you learned today.

Logical operator

&& → and Example

if a && b
#processing
end

When both a and b are true, the process is executed.

||→ or Example

if a || b
#processing
end

If either a or b is true, the process is executed.

!a true and false are opposite. Example

if !a
#processing
end

If a is really false, the process is executed. (Because false changes to true)

Use multiple logical operators in if statements

Simply put, use () to tie up a unit.

Example


if ( a && b ) || ( !a && !b )
#processing
end

||Therefore, if the left side or the right side is true, the process is executed. If the left side is "a and b is true", the left side as a whole becomes true. If the right side is "a and b are really false", the right side as a whole becomes true. The point is that if a and b match with true or false, the process will be executed. </ font>

at the end

It's like what I did in high school number A ...
