Thread: c help arrays

I am a newbie trying create an array that will sum the row and columns. I have been able to get them to display,but not total. Any help would be great.

Code:

#include <stdio.h>
void main(void)
{
  int val[5][5] = {8,3,9,0,10,
                   3,5,17,1,1,
                  2,8,6,23,1,
	       15,7,3,2,9,
	       6,14,2,6,0};
  void display (int nums[5][5]);  /* function prototype */

  display(val);
}
void display(int nums[5][5])

{
  int row_num, col_num;
  for (row_num = 0; row_num <5; ++row_num)
  {
    for(col_num = 0; col_num <5; ++col_num)
      printf("%5d",nums[row_num][col_num]);
    printf("\n");
}
}
