C help yet again..

[WorldDominator]

Sorry to keep bugging everyone out there that tries to help me...I just usually have one thing about syntax or something I don't know and it throws me off. I have yet another puzzle.

 

Wow that's small. I'll try editing. Better..

 

Now my output in the top left is supposed to look like it does in the bottom left but as you can see they look nothing similar. I used the fflush(stdout); because I referenced other material that was similar to this problem and that was done before every input. It seems to make no difference if I remove it though.

You can use sites like imgur.com to post good sized pictures on the forum.

I just fixed it. I don't have an imgur account and pretty sure you need one..right?

[prolemur]

can't wait

can't wait

is it good now Zoboomafoo?

You don't need one, I use it and I don;t remember making an account

You'll need an account to upload pictures to your profile.

Well the picture thing is handled lol. Do either of you know how to do any C programming?

 

@MikeD @random314 @Prince32780 you guys helped me on my last two. Any thoughts?

Sadly not, but I am on a course that teaches it... I'll help you in a years time.

Ask @Kuzma

I have only done c++ and a very small amount of it, sorry

I dont really udnerstand what you're trying to do though.

It sometihng's wrong with the number results, I find it helpful to print all of your variables at the end

[Kuzma]

there's a /n in there creating a new line

[Kuzma]

Scratch what I just said , try placing a space between the %s and /n so instead of being "%s/n" so "%s /n" it seems the parser is interpreting the code as you wanting the second name on a new line

lmfao was this really necessary ?! coulda warned me idk

Nope

 

My hypothesis is that it has something to do with my inputs.

[Flojer0]

Just checked an verified my suspicion. The function fgets() counts newlines as valid characters and keeps them. So you'll need to find another input function that doesn't keep the newline or remove it later in the code. I don't recall a good function to suggest but it would be good for you to look on your own anyway . If you come up empty I can figure something out.

My teacher said I had to use scanf() and fgets() for these. I didn't think scanf was really what I wanted to use where I have fgets.

[MikeD]

I always use scanf to deal with inputs when I know exactly what they are. And you usually know what they are, even if it is just a string (which can have whatever format).

In 4 years I used fgets (or its file counterpart) maybe once or twice.

so just use scanf and %s? or would I use %c? Meh I guess I can use trial and error on that

[MikeD]

It depends. Since I guess you are interested in names (char*) and grades (which appear to be doubles), it would be %s and %lf respectively.

I used %s and it works. Only problem is when I hit enter at the start of a student to print the report, it enters blank lines until i type something else and hit enter:

 

 

Student 4 last name:

 

 

 

 

 

a

 

 

*** Input Report ***

 

this is what I have where it should terminate if the user inputs just an enter

 

scanf(" %s", list[n].last);

if (strlen(list[n].last) < 1{

    break;

}

[MikeD]

That is because scanf does not recognize \n as a string (%s does not match \n).

I usually ask for (or the input provides) the number of records I have to parse to avoid exactly that situation.

Maybe in that particular case you want to use fgets to be able to read the newline...?!

 

Also, flush statements used to be necessary, but not anymore.

I thought so. The textbook must be outdated

Confession: I don't really know how to code in C

 

I do c# and some java
