And while int main(void) is the preferred way of defining a main that takes no arguments, omitting the void will usually not be an issue for main().

I kind of figured it might be the way I declared my int and yes that is c++ comments, I do not pay much attention to that it is my preferred way I leave the other to /* block comment out my code. */ for the most part, but hopefully he will read this and do one of two things update his compiler or make the needed adjustments to the code. It's not like he cannot edit it . it is just a learning process.

it is just a learning process.

Yes it is, I hope you learned something as well.

C99 is old enough to have graduated from high school, and it (if not C11) should be considered the default standard in use nowadays.

The OP hasn't indicated that this is the problem, only that "I am getting error", which is very much not helpful. My guess is that they copied the syntax-highlighted code with its non-breaking spaces and got a bunch of "error: stray '\240' in program" messages or somesuch.

yeah people really need to get updated to c99 or greater.

I agree, however since Turbo-C is still in wide use you can never take it for granted that the posters will be using modern C (but one can hope, I guess). Even gcc prior version 5 defaults to -gnu-90 and many people are still using these outdated versions of this compiler without altering the default settings.

IMO, C11 should be the target, C99 is also fairly dated.

on that note, then the posters need to embrace the ability to be able to modify the code they copy to get it work in their programs. I do, so I'll stay with that responsibility is theirs and not mine.

of course. Can't really convey sarcasm in a post.

This is where we will probably need to agree to disagree. You're the one posing as the expert, so you should be explaining what compiler options your code requires since the OP probably doesn't even know there is more than one standard, much less multiples.

I am not using any options it can compile using just gcc programName.c gets a.out I have not ran into anything in here that need extra options to compile. except when one is actually using the math header, then they've already ran their code, I am the one that needs to add -lm

I already asked OP what the errors was then you chimed in before the OP posted back. So I was not even given time to address his issues.

Still they ( OP - other people) need to learn how to modify their code to meet the requirements of their compiler, that is something they need to learn, not for me to ask if their compiler is up to date , to be sure it is not 6 years old, then post code that works on theirs.

It is still their responsibility to learn how to work through errors to get code to work on their end. If I can learn how do it without any schooling ( which sounds so cheesy) then they too can learn how to.

just like the code found online here and their that is written void main() just change it to int main then run it.
just like when an OP post scanf_s and I have to change their code to get it to run on my compiler so i can work on it to help them out with it.
this is code help not compiler help for another thing. I am not going to take myself to school to lean something that is outdated.
Their are plenty of free compilers on line that meet the C99 or higher requirements. and as the other stated it probably is just a copy paste error.
expert not, someone that might know a little more then them about what they are working on .maybe even knows what to do (and or) how to figure it out so I can show them, or try to lean them into it, even try to show them how to figure it out. OK.

Code:

userx@slackwhere:~/bin
$ gcc ./student_grades.c
userx@slackwhere:~/bin
$ ls a.out
a.out

to each his own. you teach what you know, and I'll try to teach what I know.

My goodness, all those strays! It seems your line spacings are totally messed up, you'll have to fix that... Try to pass the program through a source code formatter, it may fix it if you don't know how to remove them manually.

Are you saying that he has non-ASCII characters in his code? Is he somehow getting formatting characters or something in a copy-paste? I really have no idea what a stray error is. I've never gotten one to my knowledge.

Yes, that's what I think happened here.

That has happened to me in here as well, from copy paste OP code to examine it further.
