Thread: confused about arrays

I've already said this once, and it's starting to get repetitive: USE [CODE] TAGS!

Quzah.

I *thought* I did that already.

Consider:

Code:

#include <stdio.h>

#define MAXB 5

const char BOOKS[][18]  =  { "Automobile", "Cook",
                             "Gardening",  "History",
                             "Mystery" };

int getIndex(void);
void requestInput(int, int [],  int [], float []);
void pushData(int [], int [], float [], int []);

int main(void)
{
   
    int index, done, invt[MAXB],
                    sellp[MAXB],
                    check[MAXB] = { 0 };
                    
    float avep[MAXB];

    done = 0;

    while(done < MAXB)
    {
       index = getIndex() - 1; 
        
       if(index == 5)
          done = MAXB;
       
       else   
       {

          if(check[index] == 0)
          { 
               requestInput(index, invt, sellp, avep);
               check[index] = 1;
               done++;
          }
       
          else
             puts("\nContains data already.\n");        
       }
    }   

    pushData(invt, sellp, avep, check); 
    puts("\nDone.");

    return (0);
}

int getIndex(void)
{
   int i;
   static char myprompt[] = "1) Automobile\n2) Cook\n3) Garden\n"
                            "4) History\n5) Mystery\n6) Quit\n\n--> ";

   do
   {
       fflush(stdout);
       puts("\nSelect a book category (1-6) \n");
       printf("%s", myprompt);
       scanf(" %d", &i);

   }while(i < 1 || i > 6);

    return (i);
}

void requestInput(int i, int a[], int b[], float c[])
{
    printf("\nEnter number of %s books: ", BOOKS[i]);
    scanf(" %d", &a[i]);

    printf("Enter the sell percentage of %s books: ", BOOKS[i]);
    scanf( "%d", &b[i]);

    printf("Enter the ave price for %s books: ", BOOKS[i]);
    scanf(" %f", &c[i]);
}

void pushData(int a[], int b[], float c[], int d[])
{
    int i;

    puts("\nCategory  Stock  Avg_Price  Sell_Percent\n");

    for(i=0; i < MAXB; i++)
    {
      if(d[i] == 1)
         printf("%s\t%d\t%.2f\t%d\n", BOOKS[i], a[i], c[i], b[i]);
    }
}

You can play around with that, and see if it will help you... dunno how many bugs it has though. Use at your own risk!
