Help doing an e-mail program in c...

This is a discussion on Help doing an e-mail program in c... within the C Programming forums, part of the General Programming Boards category; .mail not .MAILR you're using: Code: fgets(ptr[i].MAILR.from,120,fp); fgets(ptr[i].MAILR.sub,120,fp); fgets(ptr[i].MAILR.msg,120,fp); fgets(ptr[i].MAILR.spc,120,fp); when it should be: Code: fgets(ptr[i].mail.from,120,fp); fgets(ptr[i].mail.sub,120,fp); fgets(ptr[i].mail.msg,120,fp); fgets(ptr[i].mail.spc,120,fp); and ...

    .mail not .MAILR

    you're using:
    Code:
     fgets(ptr[i].MAILR.from,120,fp);
     fgets(ptr[i].MAILR.sub,120,fp);
     fgets(ptr[i].MAILR.msg,120,fp);
     fgets(ptr[i].MAILR.spc,120,fp);
    when it should be:
    Code:
     fgets(ptr[i].mail.from,120,fp);
     fgets(ptr[i].mail.sub,120,fp);
     fgets(ptr[i].mail.msg,120,fp);
     fgets(ptr[i].mail.spc,120,fp);
    and also, you still have the for loop in that function. Get rid of it and just use the i value passed in to the function.

     fgets(ptr[i].mail.spc,120,fp);

    hmm..but I wanted the info coming from "mail.txt" to go to the struct mailr, and the info that the user inputs when writing an email to the struct mail..because the two have to be treatly different, as the written mails are going to be saved in the file, and the ones read from "mail.txt" have to be printf'ed in the screen, and deleted, and viewed...

    ok.....hmm

    Currently that code above is doing what you're saying. It is getting the contents of the file and storing it to your array. But it appears you want to write and read the entire array, in which case you don't actually want the index parameter for your function, just keep the for loop.

    You'll then want another function that DOES take the int variable saying which index to use and this function will delete/view/edit/whatever that particular email.

    oh..is it doing what I am saying? great then... I'll work now to see if I can get to a point where it gives no errors, and does some of the things expected, as I can't do everything that is asked for...
    thanks a lot!

    Well, I've been trying but I can't get that errors out... please jverkoey, could you give me your version that compiles with no errors? I have to have that done today at night to be delivered tomorrow, and this way I won't be able to get the grade I need to pass "Programming"... I'm desperate

    Well people, thanks for all who helped but I can't solve this problem I'm having and I'm sure that what I've done isn't enough for a positive grade... so, next year I'll have to do "programming" again... ...be well

    It's clear that you don't have a solid grasp on the areas of C that you're trying to use. To get a "positive grade" you shouldn't need to use anything that you haven't learned in class. So it seems to me that you either weren't paying attention in class or you're trying way too hard to do something that you're not ready to do.

    And there's no sense in trying to make us all feel guilty for "not helping you". We're not here to do your homework for you. Instead, you should be grateful that so many people offered so many suggestions.
    If you understand what you're doing, you're not learning anything.

    I'm not trying to accuse anybody... If it weren't you I wouldn't be able to do half of what I did... i'm only sad that maybe it isn't enough... And the work was to groups with 2 people, and my colleague quitted, so I had to make the work of 2 people, which was more difficult....
    but don't think i'm not appreciated..i really am..you were all of great help...
    be well

    Well, from what you told me last night, so far your program is just pieced together from everyone's advice given here, which in the end is a very bad thing.

    My best advice would be the following:


    1) Don't procrastinate. Programming's not the easiest stuff to do, and especially when you're on a strict time schedule and you don't know what you're doing.
    2) Do NOT ever copy code from anywhere unless you understand it. Doing this will only make you trip over yourself later on as we found last night while I was trying to help you.
    3) Make sure you know what you're doing before you jump in to making a program. I always find it best to brainstorm the ideas of a program and once I have all of the ideas in my head and the general working of the program figured out, I get to work.
