| The basic principle of for loops is that it will repeat a block of codes the number of times you specify, using not only a condition but also the initialization in the beginning and the increment at the end.
|-
|0:18-0:25
| So how much you want to increment your variable determines the number of times your variable loops by.
|-
|0.30-0.38
|So, it is a bit more complex to write. However it looks good , it does the job and its very compact.
|-
|0.42-0.43
|Now we write 'for'
|-
|0.44-0.53
|so you have got three parts of your code here,and your block and that is all you need and your content can go here.
|-
|0.54-1.03
|So, I am going to say 'echo' here and let's create a variable 'num'. So, we have echoed out 'num'.
|-
|1.04-1.13
|In here, we write num =1, not = = 1 because we are setting the variable num to the value of 1.
|-
|1.15-1.22
|Then we have a condition. For eg, while num < = to 10
|-
|1.23-1:31
|Then, we have the increment values. So, we are going to have num ++ and the loop is done.
|-
|1:32-1:37
|So, we type 'For', and our variable-num=1
|-
|1:38-1:47
|Then we have our condition 'While num< =10, the loop will continue, and then we have num ++
|-
|1:48-1:52
|As you can see this is much more useful than having num ++ down below .
|-
|1:53-1:55
|and we need not declare this up here.
|-
|1:56-1:59
|It can be declared inside these parentheses.
|-
|2:00-2:02
|O.K., I forgot the line-break.
|-
|2:03-2:07
|I’ll add a line break on to the end of this.
|-
|2:09-2:10
|Refresh.
|-
|2:11-2:12
|There you go.
|-
|2:15-2:17
|You've got your loop ten times.
|-
|2:18-2:25
|And as it has been specified in such a way it will loop only when num is less than or equal to 10.
|-
|2:26-2:28
|After that the loop will break and you may continue with the rest of the script.
|-
|2:31-2:36
|This is a bit more complex but once you learn the basics you will find it a lot easier .
|-

| Thanks for watching.
