Thread: Can't pass array to function

In this exercise there are 4 sales people and 5 products. I'm supposed to figure out how much of each product each sales person sold in a month. initSales randomly generates the sales into transaction[][][] and succeeds in doing so. The problem I'm having is with totalSales which is supposed to total all the sales for a month for every product a person sold in a month. Whenever I try to compile the program I get,

6.22.c: In function `main':
6.22.c:23: warning: passing arg 1 of `totalSales' from incompatible pointer type
6.22.c:23: warning: passing arg 2 of `totalSales' from incompatible pointer type

What am I doing wrong?

Code:

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

#define PERSON 5
#define PRODUCT 6
#define DAY 31

void initSales( int [][][] );
void totalSales( int [][], int [][][] );




int main()
{
   int transaction[ PERSON ][ PRODUCT ][ DAY ] = { 0 };
   int sales[ PERSON ][ PRODUCT ] = { 0 };

   srand( time(NULL) );

   initSales( transaction );
   totalSales( transaction, sales );


   return 0;
}





void initSales(int var[][ PRODUCT ][ DAY ])
{
   int i, j, k;


   for (i = 1; i <= PERSON - 1; ++i) {
      for (j = 1; j <= PRODUCT - 1; ++j) {
         for (k = 1; k <= DAY - 1; ++k) {
            var[i][j][k] = rand() &#37; 1000;
            /* test statement below */
//          printf("person: %d\nproduct: %d\n day: %d\nsold: %d\n\n", i, j, k, var[i][j][k]);
         }
      }
   }

return;
}





void totalSales( int sumofSales[][ PRODUCT ], int transactionsMade[][ PRODUCT ][ DAY ] )
{
   int a, b, c;


   for (a = 1; a <= PERSON - 1; ++a) {
      for (b = 1; b <= PRODUCT - 1; ++b) {
         for (c = 1; c <= DAY - 1; ++c) {
            sumofSales[ a ][ b ] += transactionsMade[ a ][ b ][ c ];
            /* test statement below */
            printf("person: %d\nproduct: %d\nsold: %d\n\n", a, b, sumofSales[ a ][ b ]);
         }
      }
   }


return;
}
