This article mainly shows you "What are the basic Perl operators?" The content is simple and easy to understand, and the organization is clear. I hope it can help you solve your doubts. Let Xiaobian lead you to study and learn "What are the basic Perl operators?" This article.

numeric operator

+、-、*、/、%、**、++、--、+=、-=、*=、/=

..、.、x、，

@a = (1 .. 4); # @a = (1,2,3,4), note: cannot be from large to small

$s = "Test". 1; # $s = "Test1"

$s .= 2; #$s = "Test12"

@a = (1) x 4; # @a = (1,1,1,1)

$s = "A" x 4; # $s = "AAAA"

my ($a,$b) = (1,2); # my $a = 1; my $b =2;

$a=$b+1,$b=$a+1; # $a=$b+1;$b=$a+1;

($a,$b) = (1,2);

($a,$b) = ($b+1,$a+1); # $a=3, $b=2

#is not equal to: $a=$b+1; $b=$a+1;

logical operators

Logical OR: $a|| $b or $a or $b #either a or b is true

logical AND: $a && $b or $a and $b #true only if both a and b are true

Logic is NOT: ! $a or not $a #a is true when false

Logical XOR: $a xor $b # a, b is true when one is true and one is false

Conditional operators (ternary operators):

Conditions? Value1: Value2. When the condition is true, the value is 1, and when it is false, the value is 2, such as:

$result = ($var == 0) ? 14 : 7;
