Perl FOR Loop Function

What is For loop function in Perl programming?


The For loop function in Perl is to repeat a set of statements based on the given conditions.


for (initial value; test value; increment value )
Statement to be executed

In the above syntax "initial value" is the starting value, "test value" specifies the test condition, "increment value" specifies the increment value based on which a set of code is executed.

Example :

#! C:programfilesperlbinperl
print "content-type: text/htmlnn";
for($row = 1; $row < 4; $row++)
print "This is line $row.";
Result :

This is line 1.This is line 2.This is line 3.

In the above example the a number range from 1 to 3 is printed, by incrementing value by 1 using the for loop with a print statement.
