c program to find maximum element in array

This code find maximum or largest element present in an array. It also prints the location or index at which maximum element occurs in array. This can also be done by using pointers (see both codes).

C programming code

#include <stdio.h>
 
int main()
{
  int array[100], maximum, size, c, location = 1;
 
  printf("Enter the number of elements in array\n");
  scanf("%d", &size);
 
  printf("Enter %d integers\n", size);
 
  for (c = 0; c < size; c++)
    scanf("%d", &array[c]);
 
  maximum = array[0];
 
  for (c = 1; c < size; c++)
  {
    if (array[c] > maximum)
    {
       maximum  = array[c];
       location = c+1;
    }
  }
 
  printf("Maximum element is present at location number %d and it's value is %d.\n", location, maximum);
  return 0;
}

C programming code using pointers

#include <stdio.h>
 
int main()
{
  long array[100], *maximum, size, c, location = 1;
 
  printf("Enter the number of elements in array\n");
  scanf("%ld", &size);
 
  printf("Enter %ld integers\n", size);
 
  for ( c = 0 ; c < size ; c++ )
    scanf("%ld", &array[c]);
 
  maximum  = array;
  *maximum = *array;
 
  for (c = 1; c < size; c++)
  {
    if (*(array+c) > *maximum)
    {
       *maximum = *(array+c);
       location = c+1;
    }
  }
 
  printf("Maximum element is present at location number %ld and it's value is %ld.\n", location, *maximum);
  return 0;
}
