Thread: Major Problem

Program keeps reading students up to 30. Saves into file 'student.dat' record is
char sLastName[20]
char sId[6]
char sMark[3]
int iMark
User enters mark as integer program fill in sMark with letter grade
Here is my work
After awhile I started to comment out bits of code but no help







#include <string.h>
#include <stdio.h>
#include <stdlib.h>


struct class
{
char sLastName[20];
char sId[6];
char sMark[3];
int iMark[];
};

void EnterRecord(struct class*)

int main(void)
{
struct class student[30];
int iIndex = {0}, iNumber = 0, iMark = {0};
char cAnswer;
char /*cLetter ={0}, cChar ={0},*/ sName = {0}, sStuId ={0}, sMark = {0};



printf("Would you like to enter a student record?");
scanf(" %c", &cAnswer);

while (cAnswer=='y' || cAnswer=='Y')
{

printf("Enter student name, Id, mark: ");
gets(student->sLastName, student->sId, student->iMark, student->sMark );

sMark = EnterRecord(/*int iStuId[],*/ student, iMark[] , sMark[]/* char cLetter[], char cChar[]*/)

printf("Student Name: %s, Id: %s, Mark: %i, Grade: %s\n", student.sLastName,
student->sId, &student->iMark, student->sMark);

++iIndex;
printf("continue Processing?");
scanf(" %c", cAnswer);
}
}



/************************************************** ************************/

EnterRecord( &student)
{ int iNumber, iIndex;
char sMark;

iNumber = iMark[iIndex] ;


if (iNumber < 50)
{
sMark[iIndex] = "F"
/*cChar[iIndex] = 32; */
}

if (iNumber >= 50 && iNumber <= 52)
{
sMark[iIndex] = "D-";
/*cChar[iIndex] = '-';

return sMark;

30 id max. user can quit ant time

Dear Kalski

I am a bit interested in your problem, though cannot say that I fully understand it. Please say more about what the programme is supposed to do and what it does. Also confirm that this is a C or C++ programme.

I noticed that the code submitted does not have any writting to file coding. Was that intentional ?

Wait to hear

c program
write a file stucture that keeps reading student records(up to 30) and saves into student .dat. Each record has the following info
char sLastName[30]
char sId[6]---student id is 5 char string
char sMark[3]----letter grade based on numeric mark
int iMark-----numeric mark

If you copy my code to a compiler you see how disjointed it is.
Have to give this in tonite
thanks for the help
