Noob needing help with large C assignment

Hi, I am a complete noob with C programming and was recently assigned a project for my class that is really overwhelming me. Compared to my other assignments, I just have no idea where to start with this one and what to do in it. Any help or advie on where to start or how you would go about doing the program would be greatly appreciated. I don't want to come off as wanting you guys (Or girls) to do the program for me, but rather to help give me a strong push in the right direction. Thanks a bunch!

What are your efforts so far, in terms of code or thinking - What is the source file for? It seems to be an answer from your tutor.

Step 1 on a Large assignment is to start on it early.

After you start work on this assignment, then start asking smart questions on your problems.

The source code is what I have to update in order to fulfill the requirements set by my teacher. Basically he gave us a code and wants us to update it to do more things.

So far I have been thinking rather basically. For instance, to meet the first requirement I would just state a new char in the "Struct Student" that would be labelled like

insert

Code:

---

    char letterGrade;

---

and then I would use it later on to record the letter grade that the numeric grades computed refer to in the "compute_averages" function

Then, for the second part of the assignment, I thought to use a do while loop to have the user input a decimal which represents the percentage of the student's average that is comprised of the final exam. Also, I would declare another variable, z, to hold the floating point value. Something like

insert

Code:

---

    do
    {
          printf("Enter the decimal that corresponds to the percentage of the student's average that is     
                      comprised of the final exam grade: ", %f)
          scanf("%f", &z)
    } while( (z < 0) || (z > 1))

---

After that, for the second part of the requirement I would use a series of if, else if, and else statements to get a letter grade for the student, like this

insert

Code:

---

    if (z >= 90)
          letterGrade = 'A'
    else if (z >= 80)
          letterGrade = 'B'
    else if (z >= 70)
          letterGrade = 'C'
    else if (z >= 60)
          letterGrade = 'D'
    else
          letterGrade = 'F'

---

I honestly don't even know where to start on numbers 3, 4, and 5, as the way he formatted it is throwing me off as to what each part of that code really corresponds to in the final project. Any help you can give on how to just start off on the journey to working on those would be greatly appreciated. Also, sorry for the fact that I couldn't use the online code insert thing but my tablet doesn't seem to allow me to use that feature of the site

Paste in the the full code with your updates and any compiling errors and the forum can better assist and attack items individually. Looks like your instructor has done all the fancy coding for you guys already and its just a matter of additions.

You're spot on with #1, that's a easy one.

As for #2...
I'm unclear about this, but does the user defined fraction between 0 & 1 need to multiply against the final average?

As for the letterGrade part, remember you need to manipulate the value within the STUDENT structure.
