Largest Element of Array

Largest Element Of Array

An array element which has the highest numerical value among all the given elements in an array is referred to as the largest element of the array.

Syntax

[arr_size]={value 1, value 2, value 3,…,value n-1};

Algorithm

Step 1: Start
Step 2: Initialize arr[]
Step 3: Length = sizeof(arr)/sizeof(arr[0])
Step 4: Large = arr[0]
Step 5: Set i=0
Step 6: Repeat Step 7 and 8 till i < length of an array
Step 7: If(arr[i] > Large) Large = arr[i]
Step 8: i = i + 1
Step 9: Print the Largest element from an array
Step 10: Return 0
Step 11: End

Working Of Program

In all these following programs, we’ll learn to display the largest numbers or elements among all the given elements from the array.

Pointers in C

Pointer to arithmetic in C

Null pointer

Function pointer

Pointer v/s array

Problem 1

Write a program using an array for displaying the largest element from the array.

Firstly, enter the number of elements of an array.
Then enter all the elements of an array.

Code

Run

#include<stdio.h>
int main ()
{
  int n;
  double arr[1000];
  printf ("Enter the number of elements (1 to 1000)= ");
  scanf ("%d", &n);
  for (int i = 0; i < n; ++i)
    {
      printf ("Enter number %d = ", i + 1);
      scanf ("%lf", &arr[i]);
    }
  for (int i = 1; i < n; ++i)
    {
      if (arr[0] < arr[i])
	{
	  arr[0] = arr[i];
	}
    }
  printf ("Largest element = %.2lf", arr[0]);
  return 0;
}

Output

Enter the number of elements (1 to 1000)= 6
Enter number 1 = 67
Enter number 2 = 90
Enter number 3 = 89
Enter number 4 = 679
Enter number 5 = 88
Enter number 6 = 999
Largest element = 999.00

Problem 2

Write a program using an array for displaying the largest element from the given array.

Code

Run

#include<stdio.h>
int largest (int arr[], int n)
{
  int i;
  int large = arr[0];
  for (i = 1; i < n; i++)
    if (arr[i] > large)
      large = arr[i];
  return large;
}
int main ()
{
  int arr[] =
    { 26078, 436, 904, 23, 75, 936, 777, 684, 927, 2, 8967, 5467, 34 };
  int n = sizeof (arr) / sizeof (arr[0]);
  printf ("Largest element in given array = %d", largest (arr, n));
  return 0;
}

Output

Largest element in given array = 26078

Problem 3

Write a program using function to find the largest number or element of an array.

Code

Run

#include<stdio.h>
int max (int arr[], int size)
{
  int max = arr[0];
  for (int i = 1; i < size; i++) { if (arr[i] > max)
	max = arr[i];
    }
  return max;
}

int main ()
{
  int size;
  printf ("Enter Size of Array = ");
  scanf ("%d", &size);
  int arr[size];
  printf ("Enter Array Elements = ");
  for (int i = 0; i < size; i++)
  scanf ("%d", &arr[i]);
  printf ("Largest Element = %d", max (arr, size));
  return 0;
}

Output

Enter Size of Array = 5
Enter Array Elements = 11
22
33
44
55
Largest Element = 55
