Find maximum element of each row in a matrix

Here given code implementation process.

//C Program 
//Find maximum element of each row in a matrix
#include<stdio.h>

//Matrix size
#define ROW 4
#define COL 4

//print max element in each row
void row_max_element(int arr[][COL])
{
  int result=0;

  for (int i = 0; i < ROW; ++i)
  {
    //Get first element of i row
    result=arr[i][0];

    for (int j = 1; j < COL; ++j)
    {
      if(result<arr[i][j])
      {
        //Get new max element
        result=arr[i][j];

      }
    }
    printf(" %d\n",result);
