示例 1：

Perl

#!/usr/bin/perl -w
 
# Defining a string
$string = "Geeks For Geeks";
 
# Defining an array of Integers
@array = (10, 20, 30, 40, 50, 60);
 
# Searching a pattern in the string
# using index() function
$index = index ($string, 'or');
 
# Printing the position of matched pattern
print "Position of 'or' in the string $index\n";
 
# Printing the defined array
print "Array of Integers is @array\n";

输出：

Position of 'or' in the string 7
Array of Integers is 10 20 30 40 50 60

示例 2：

Perl

#!/usr/bin/perl -w
 
# Defining a string
$string = "Welcome to GFG";
 
# Defining an array of integers
@array = (-10, 20, 15, -40, 45, -60);
 
# Searching a pattern in the string
# using index() function
$index = index($string, 'o G');
 
# Printing the position of matched pattern
print "Position of 'o G' in the string $index\n";
 
# Printing the defined array
print "Array of Integers @array\n";

输出：

Position of 'o G' in the string 9
Array of Integers -10 20 15 -40 45 -60
