I tend to do this out of habit: though it's sometimes annoyingly pedantic, it's a great way of finding potential logic errors of the type that can sometimes take days to track down otherwise...

As for declaring main() as void, that's something that I seem to have dredged from my memory that could've happened at any time in the last 25 years! I think I had a moment's uncertainty as I tend to mainly use BSD Unix for compilations these days and I'm not sure if that tends to rigidly follow the standards elsewhere or not (or vice-versa, depending).

And as regards implicit returns, at least you don't see something I discovered with a compiler (whose creator shall remain nameless) quite a few years ago that would fall through the bottom of a procedure and start executing the next one unless an explicit return statement was present. That was... disconcerting. And very broken.

That's like a second language and I admire anyone that can understand it because when I look at that sort of thing all I think is

Hello, again. It seems I ran into another small problem.

My task this time is to create a counting program that counts from 1 to 100 in increments of 5.

So far I have this...

#include #include main(){for( int k = 1; k<=100; k+=5 )}

I get an error about C99 mode or something like that. After doing some research I learn that I am suppose to insert C -std=c99 somewhere in my code? I add it in but I just get more errors and it refuses to compile. Can someone tell me what is wrong here?

Your loop does not really do anything and it's missing the brackets {}, but somehow I'm not sure is it that. Missing semicolon, shrugs? And your main function is missing either int or void return type. Then if you return an int, main would need to end in return 0;. I can't remember what ctype.h includes.

Questioning someones decision of programming language is usually frowned upon, but I must ask, why C?

Also, you should add a printf (is it printf?) statement within the for-loop, displaying the variables current value at every loop.

Believe me, I don't want to do this crap but it is a required course for web design...

lol, I feel for you :brokencomputer:

You need to declare k separately, not within the for loop.

Edit: and not forgetting that it needs to do something, such as "printf("k=%d\n", k);", or at least be terminated with a semicolon.


Why not? :unsure:

Ohh, right, that too, but it would work as is in C++, I think.

Well, unless you intend to make some highly-optimized or resource-hogging software, it really aint neccessary.

I am still getting this error about "loop initial declaration used outside c99 mode".

I'm not entirely sure what to say in response to that. Optimised code is always desirable, and there are worse ways to teach it than with C; given that it forms the basis for many other contemporary programming languages, it's not a bad place to start.

Having used it for the past 25 years I'm aware of its limitations and like any other tool it's not necessarily ideal for every situation, but it doesn't make a lot of sense to write it off so quickly.
