rank

How do i store students data in 6 different files. show the time they arrive for school. rank them by there grades. student's data must be store using a structure

Code:

#include<stdhomework.h>

That's pretty much all you need for this. Isn't C great?


Quzah.

so what else u need to do

We try to help people with actual code. If you REALLY have no idea, then you need to review your chapters in the book, along with your class notes, and other programs you've written. The C tutorial link near the top of the forum, may be a big help, as well.

It's disconcerting to have someone ask for help to overhaul their car's engine, when you find out they barely know a screwdriver from a socket.

In any case, if you want help with pseudo code, post what you have, and ask specific questions about what you need help with. If you want help with a program, post your code, and ask specific questions so we know what you're stuck on.

But we don't take an assignment and start writing up code for people.

Read the Homework announcement.

Dumbass.

clam down memcpy

Do you want the data stored in one Structure, then distributed to 6 different files?

yep i do

Where is the data coming from, is the user supposed to enter in all the data and then you store it?

Code:

#include<stdio.h>
#include<time.h>
#include<math.h>
int avg(int x, int y, int a);//Funcation prototype to find average
int oavg(int x, int y, int b, int a);// Function prototype to the overall grade average
    /*student data Structure definition*/
struct studentdata{   
      float egrade;//Students english grade for term 1
      float mgrade;//Students math grade for term 1
      float egrade1;//Students english grade for term 2
      float mgrade1;//Students math grade for term 2
      float egrade2;//Students english grade term 3
      float mgrade2;//Students math grade  term 3
      char sex[9];//Gender
      char fname[30];//first name
      char lname[30];//last name
      int age;//Age
      int schfee;//School fee payment
      char pa[2];//To show pm or am
      int late;//The amount time student was late
      int abs;//Amount time student was abscent
      float z;//Use to hold the values of the averages when calculating the averages
      float a1;//Term 1 average grade
      float a2;//Term 2 average grade
      float a3;//Final term average grade
      float oga;//Overll grade averAge 
      int id;//Identification Number
      };

How do i put a function prototype and definition within this program to rank the students base on there grades

Where did you get that code from?

Did you copy/paste the code from case 6 to case 7 ?

Was the only edit to change gradeI into gradeII ?

If so, then make it a function where you pass say
outputRecord( gradeI, student );

and make the code a hell of a lot shorter into the process.
