C Programming Tutorial #20, Find maximum element in array

20
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). The algorithm to find maximum is first we assume that maximum element occurs at beginning of array and stores that value in a variable. Then we compare it with other array elements one by one, if any element is greater than our assumed maximum then maximum value and index at which it occurs is updated. Similarly we can find minimum element in an array.

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 %d and it's value is %d.\n", location, maximum);
  return 0;
}
