#6.1 LOOPS or ITERATORS and Loop Control Statements Video Lecture | Kotlin Tutorial for Beginners: Learn Kotlin in easy language - Back-End Programming

hi registering Siddarth and welcome to
the next video of this course of
Cortland programming series now in this
video we will learn about the I traitors
in case of Cortland now similar to Java
and any other programming language we
have for loop while loop and do-while
loop in case of Cortland and also we
have break and continue statement to
execute our code as per our wish now
first of all why do we need loop so as a
beginner you might ask this question now
suppose you want to print hello so it is
perfectly fine you can simply type print
line hello now you want to print hello
let's say multiple times so you will
simply type print line hello
multiple times and in the output as well
you will get hello
four times right as a beginner you will
go for this option but let me tell you
this is not the way to do it if you have
same kind of patterned output then in
this situation we have to make use of
loops or you can say the I traitors now
here let us check out what are the
syntax of for loop while loop and
dowhile loop now increase of for loop we
have this syntax for followed by
function I in this is the ranges now
this one dot dot four is actually the
range that we already saw in the
previous video so I in one dot dot for
that simply means I will have the value
of one two three and four now inside
this let us print hello four times like
this now similarly while loop has its
own syntax such as while I is smaller
than five now here I is actually the
counter variable now inside the while
loop we can simply print hello and then
increment the counter variable I plus
plus and now at the end we have do-while
loop here what I will do the syntax is
do followed by curly braces and here we
have wild that will simply check for the
condition and now inside this we can
simply print hello and then increment
the counter so the syntax of do-while
loop and while loop is exactly same as
that of java the only difference we will
find is in
Ace of for-loop right and now let us
check out the structure of the loop so
inside the loop structure we have one
counter variable like I and I here and
also here
right and now next we have a condition
check now in case of for loop and while
loop first we are checking the condition
and then only we are executing the code
but in case of do-while loop we are
first executing the code and then
checking the condition right and then at
last we have incrementing and
decrementing of the counter such as here
isis plus I plus plus and here as well
in case of for loop it is actually
getting incremented internally so this
was all about the syntax of for loop and
while loop and also do-while loop now
next let us proceed and check out the
loop control statements in case of
Cortland so in Cortland we have the
break statements continue statements and
also the return statements that I will
talk about it shortly
