    i am suppose to print the books using string, but wud have to use array, i tried it but its not working, and also for each of the books , an address shud be printed, i tried that using a pointer but is only printing one general address, wud writing the books as string be a form of structure?. here is ma source code
    Code:
    #include <stdio.h>
    #include <conio.h>
    
    
    int discount (int x);
    int tax (int y);
    
    
    main ()
    {
    
    
        int code[10];
       int i,after_discount;
       float after_tax;
       int total;
       int cost=500;
       float date;
    
    
       printf("Enter the date the books were purchased mm.yyyy\t");
       scanf("%f",&date);
    
    
       for (i=0;i<10;i++){
           printf ("Enter the book code:\t ");
          scanf ("%d", &code[i]);
          }
    
    
       total = 500.00 * 10;
       after_discount = total - discount (cost);
       after_tax = after_discount + tax (total);
    
    
       clrscr();
    
    
     printf ("**************************Triple S&T Bookstore****************************\n");
    
    
      printf( "%10s%45s\n", "***BOOKS***", "***CODES***" );
    
    
       printf ("A Painted House\t %35d\n", code [0]);
       printf ("The Firm\t %35d\n", code [1]);
       printf ("The Testament\t %35d\n", code [2]);
       printf ("Pelican Brief\t %35d\n", code [3]);
       printf ("Runaway Jury\t %35d\n", code [4]);
       printf ("Rain Maker\t %35d\n", code [5]);
       printf ("Street Lawyer\t %35d\n", code [6]);
       printf ("A Time to Kill\t %35d\n", code [7]);
       printf ("The Confession\t %35d\n", code [8]);
       printf ("Bleachers\t %35d\n", code [9]);
    
    
    
    
    
    
      printf ("*************************************************************************\n");
    
    
    
    
    
    
       printf ("Discount is:$ %d\n", discount(cost));
       printf ("After discount:$ %d\n",  after_discount);
       printf ("Tax is :$ %d\n", tax (total));
       printf ("Total Amount to be paid:$ %.2f", after_tax);
    
    
    
    
    
    
    getch ();
    return 0;
    }
    
    
    int discount ( int x)
       {
       int four_books,discount;
        four_books = x * 4;
        discount = 0.10*four_books;
        return discount;
        }
    
    
    int tax (int y)
        {

    you are posting in the wrong forum - and please dont write in baby language - wud cud shud ma etc
    i am sorry but your code is a bit messy- write small experimental 'test' programs that do what you expect to try out the features you need to use
    use int main()
    dont use turbo c compiler or its outdated headers
    INITIALISE variables

    And consider - if your program has values that are never meant to change then show that - use define statements and CAPITAL letters for the name of that data - its a message to you (and other programmers) that the names in CAPS are constant values like your tax rate - which by the way cannot be an int - though i would like my tax to be calculated like that - 0% or -1% is what i would like to pay for sure

    Moved to C forum.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
