Some help with a program.

Hi there,

I need some help with a program I am writing:

Write a program that will allow the user to enter the results of TEST1 for (Computing Systems and Programming) subject and store them in a data file named TEST1.txt. The data file “TEST1.txt” should have the following format:

Code:

Matric No.            Name		      Marks

And this is what I've done so far:

Code:

#include <stdio.h>
#include <stdlib.h>
//#include <cstring.h>
#define FILENAME "data.txt"
int main (void)
{
     int num;
     printf ("How many students would you like to place record for?\n");
     scanf  ("%d", &num);
     
     char name;
     int matric;
     double marks;
     
     FILE *datatab;
     datatab = fopen (FILENAME,"a");
     
     if (datatab == NULL)
        printf ("Error opening File\n");
     else
     {
     printf ("num = %d\n",num);
     int i = 0;   
        while (i<num)
        {
            printf ("i = %d\n",i);
            printf ("Please Enter name(Less than 50 Characters:\n");
            fflush(stdin);
            scanf("%s", &name);
            fflush(stdin);
            
            printf ("Please Enter Matric Number:\n");
            scanf("%d", &matric);
            
            fflush(stdin);
            printf ("Please Enter Marks Obtained (via Cheating or otherwise):\n");
            scanf("%f", &marks);
            
            fflush(stdin);
            
            fprintf (datatab,"%d %s %.2f\n", matric,name,marks);
//            fflush(stdin);
            i++;
        }
     fclose(datatab);     
     }     
     system("pause");
     return 0;    
}

I have been trying to fix the code so you may or may not need the commented lines. What I would like to know is what's wrong and why it can't produce the required output.

Matric number ex: 0987674 (I want the zero to be displayed)
Name ex: Anything (Just the first name would be enough).
Marks ex: 67.89 (Maximum of 2 digit decimal)

Try compiling with warnings on. That'd point you in the right direction.
1. fflush wasn't designed to work on input streams.
2. name is only a single character.


Quzah.

How do I enable warnings in Dev C++?
