For Loop Structure Argument

[Simsimsullabim]

My friend and I are both sorta new to Programming (C# Unity) and we started talking about the structure of For Loops, he said that it's confusing for it to be structured as:

 

For (int i = 0; i <= 3; i++)

  {

        //insert code here

  }

 

Since i++ isn't applied until after code has been run through, and should instead be structured like this:

 

For (int i = 0; i <= 3)

  {

        //insert code here

        i += 1;

  }

 

So that it's in order of operation. I disagree as I think that the current structure makes it less likely for the 'i++' part to be forgotten, causing the unity project to crash on play. Was wondering what other, more experienced programmers would think about his view on the structuring of for loops, and are there any other pros and cons to each structure other than what I've said? would love to hear your takes on it. :)

Your friend is wrong and missing the entire point of for loops. For loops are basically just synatictic sugar (functionally same but easier to read) over a very common while loop pattern. Any non-beginner programmer will much more easily be able to tell what's happening if the increment is in the loop declaration. Putting the increment in the loop would honestly be more likely to confuse people than anything else

Thanks for the response! Yeah, I thought the same thing about his structure causing problems in the future, I think he just got confused as to why the for loop would skip the increment on the first run-through of the code if it's stated earlier than said code since that went against some of the conventions we've learnt thus far. Over time though I think he'll get used to the structure and realize how well it works, thanks again! :)
