Thread: Two compile errors i need help with.

Hi,

I am trying to write a program (exercise from a book) that reads in information about salespersons and products they sold and summarize output in tabular format. I am nearly there, when i compile it there are lots of errors (i'm very new 2 c, about 2 weeks), and later i fixed all of them except for two. Pls spot them for me. Thnx in advance! Also if possible, is there a way to make the code even better? Thnx again.

Code:

/* Read in salesperson and product information,
   process them and output in tabular format. */

#include <stdio.h>
#define PERSON 4
#define PRODUCT 5

/* Function prototype */
void output( const int array[][ PRODUCT ], int person, int product );

int main()
{
   int sales[ PERSON ][ PRODUCT ] = { 0 };
   int i, j;                                  /* Loop counters */

   for ( i = 0; i <= PERSON - 1; i++ ) {
      for ( j = 0; j <= PRODUCT - 1; j++ ) {
         printf( "Enter cost of product %d for sales-person %d (Enter -1 if nothing): ",i, j);
         scanf( "%d", &sales[ i ][ j ] );     /* Store input in array */
      }
      printf( "\n" );
   }

   output( sales, PERSON, PRODUCT );                            /* Print summary */

   return 0;
}

void output( const int array[][ PRODUCT ], int person, int product )
{
   int i, j, k, total = 0;

   printf( "\n            ***Report***\n" );   /* Print title */

   printf( "%s%4s%4s%4s%6s", "Person 1", "Person 2", "Person 3", "Person 4",
           "Totals" ); /* Column headers */

   for ( i = 0; i <= person + 1; i++ ) {
      printf( "\n" );
      printf( "Product %d", i );
      if ( i != 4 ) {
         for ( j = 0; j <= product; j++ ) {
            if ( array[ i ][ j ] == -1 )
               printf( "%4s", "/" );
            else {
               printf( "%4d", array[ i ][ j ] );
               total += array[ i][ j];
            if ( j == 4 )
               printf( "%4d\n", total );
         }
       total = 0;
      }
   }

   printf( "\nTotals" );
   printf( "%4d", array[ 0 ][ 0 ] + array[ 0 ][ 1 ] + array[ 0 ][ 2 ] + array[ 0 ][ 3 ] + array[ 0 ][ 4 ] );
   printf( "%4d", array[ 1 ][ 0 ] + array[ 1 ][ 1 ] + array[ 1 ][ 2 ] + array[ 1 ][ 3 ] + array[ 1 ][ 4 ] );
   printf( "%4d", array[ 2 ][ 0 ] + array[ 2 ][ 1 ] + array[ 2 ][ 2 ] + array[ 2 ][ 3 ] + array[ 2 ][ 4 ] );
   printf( "%4d", array[ 3 ][ 0 ] + array[ 3 ][ 1 ] + array[ 3 ][ 2 ] + array[ 3 ][ 3 ] + array[ 3 ][ 4 ] );

   for ( k = 0; k <= 50; k++ )
      printf( "*" );
   printf( "\n" );
