#include <stdio.h>

#include <stdlib.h>

int main (void)

{

     int *ar, *max;

     int i;

     //Create array

     ar = (int *) calloc (20, sizeof (int));

     if (ar == NULL)

     {

          printf ("Error! Memory not allocated.");

          return 0;

     }

     //Input elements

     printf ("Input elements: ");

     for (i = 0; i <= 19; i++)

          scanf ("%d", ar + i);

     //Find largest

     printf ("Largest: ");

     max = ar;

     for (i = 1; i <= 19; i++)

          if (*(ar + i) > *max)

               max = ar + i;

     printf ("%d", *max);

     return 0;

};

Output

Input elements: 5 20 2 17 4 10 11 3 8 13 9 14 6 1 16  7 19 15 12 18

Largest: 20
