hi.....programmers!......

hi.....fellow pfogrammers!.....my name is shiva harrinanan and i'm a first year computer science student at uwi....i'm a bit green with respect to this field but its an interesting field and i really want to become part of it.....

 

Hi Shiva and welcome to the forum

 

Re: hi.....programmers!......need some help below

Code:

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

struct Student
{
   char   sId[10];   // student ID
   char   fName[30]; // student's first name
   char   lName[30]; // student's last name
   int    m, p, c;   // m = maths, p = physics, c = chemistry
   // m, p, and c belong to the range [0..10]
   double avg; //average mark with 1 digit after decimal point
};

i really need some help....i'm stuck.....

 

basically i wanna write a simple C program of student management system using an array of structures...it suppose to give the user some options but as you can see, i'm fresh out of ideas...any input will be deeply appreciated...thanks
