This is an assignment question that I need assistance with.

'Write a simple address-book program that uses a function to read in the name, address and phone-numbers of BOOK_SIZE people (where BOOK_SIZE is a macro) and stores these values in an array of structures. Write another function that neatly displays this data in a table on the screen. Pass the array as an arguement to these functions.'

Well, I don't know what is your question exactly so I'll write a source code that should do the trick :

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

#define BOOK_SIZE 5 /* Define the BOOK_SIZE macro */

struct T_BOOK  /* Define the Book structure type*/
{
  char name[50], number[15], address[100];
};

void getbook(struct T_BOOK book[]);
void showbook(struct T_BOOK book[]);


void main(void)
{
  struct T_BOOK book[BOOK_SIZE]; /* Define a book varible */
  getbook(book);
  showbook(book);
  return(0);
}

void getbook(struct T_BOOK book[])
{
  int i;

  for (i = 0 ; i < BOOK_SIZE ; i++)
  {
    clrscr();
    printf("Enter name #%d:\n",i+1);
    gets(book[i].name;      
    printf("Enter number #%d:\n",i+1);
    gets(book[i].number;
    printf("Enter address #%d:\n",i+1);
    gets(book[i].address;
  }
}

void showbook(struct T_BOOK book[])
{
  int i;

  clrscr();

  for (i = 0 ; i < BOOK_SIZE ; i++)
  {
    printf("Name #%d: %s\n", i, book[i].name);
    printf("Number #%d: %s\n", i, book[i].number);
    printf("Address #%d: %s\n", i, book[i].address);
    if ( (i+1)*3 == 24 ) { getch(); clrscr(); }
  }
}


Thats it. Thats the program. It reads BOOK_SIZE names to a BOOK_SIZE array of type T_BOOK structure, which contains name, number and address. Then it shows everything and pauses every 24 lines so you won't miss any.
Hope this helps.
