makes pointer to integer without cast

Question

I'm having a bit of a problem with my code. The compiler is telling me that my code is making a pointer to an integer without a cast. Now I'm not familiar with what this means so maybe someone could point (pun very intended) me in the right direction. Also any general tips would be much appreciated!

The exact error is:

Homework3.c: In function ‘main’:
Homework3.c:32: warning: passing argument 1 of ‘add’ makes pointer from integer without a cast
Homework3.c:16: note: expected ‘int (*)[5]’ but argument is of type ‘int’

Answer 1

sales[SALESPERSON][PRODUCTS] returns the integer at position PRODUCTS of the array referenced at position SALESPERSON in sales. You just need to pass sales:

add(sales, data, totals); //same thing with totals

You also don't give the length of the array for the function, so your definition should just be:

void add(int[][] sales, float data, float[] totals)
