Hi all,
I have a program that I need help on. I have attatched it to this thread-it is a Student Record program that is meant to read in details of a student from a binary file -store this data(put it in structure in memory) then allowing the user to input 4 test marks working out the average.
Then it is worked out whether the student has passed/failed-then the details are written to Passed.txt or Failed.txt.
Thanx, much appreciated.

I won't give up all the answers, but here's a biggie:
You begin defining a structure, but forget to actually "complete the thought" before you move on to your prototypes. Also, STUDENTSlist appears to be an array, but an array of what?Code:typedef struct { STUDENTSlist[RECORDS]; int GetStudentRecord(void); /* Reads list from file */ int EnterandCalcResults(void); /* Enters marks & calculates results */ int find(char*,int); /* Searches list for entry */ void WriteToTextFile(int); /* writes updated list to file */
Good luck.

Thanx for your reply Deckard, well its a question of whether I need an array for the records.
Right here is the whole program - any input will be HIGHLY praised-please before the end of today-I will be forever in debt to you........

#include <conio.h>
#include <stdlib.h>
#include <string.h>
#include <alloc.h>

#define FILE_OUT"Passed.txt"
#define FILE_OUT2"Failed.txt"
#define RECORDS 25
typedef struct {
char Fname[32]--------details of chars--------------- ;
int ID[7]-------;
}STUDENTS;
STUDENTS list[RECORDS];

and so on...........for all chars.....

scanf("%d",&a[j]);

if (av>=0)&&(av<=39) then
printf("GRADE=E\n");
----------and so on to give overall grade----------
void WriteToTextFile(int){

The rest of the code should write details to appropriate text file-either of two
CAN ANYBODY HELP ME?????
