Q. Write a program to find largest element in an array.

Solution :- In this program, we will find the largest/Maximum value element in an array.

For Example :-
input : arr[]={ 8, 9, 1, 2, 4 }
output : 9

So as we can see that the largest element in arr[] = {8, 9, 1, 2, 4 } is 9 so the output is 9.

Largest Number Algorithm

START
Step 1 → Take an array Arr and define its values
Step 2 → Declare one variable (VAR) and assign 1st element of array to it
Step 3 → Loop for each value of Arr Repeat Step 4
Step 4 → If Arr[I] > VAR, Assign Arr[I] to VAR
Step 5 → After loop finishes, Display VAR which holds the largest element of array

Largest Number Program

  • C
  • C++
  • Java
  • Python
  • C#
  • PHP
    • #include <stdio.h>
int main() {
int i, arr[5]={ 7, 9, 1, -15, 0};
int VAR = arr[0];
for (i = 1; i < 5; ++i) {
if (VAR < arr[i])
VAR = arr[i];
}
printf("Largest element in an Array is = %d", VAR);
return 0;
}

    #include <iostream>
using namespace std;
int main()
{
int i, arr[5]={ 7, 9, 1, -15, 0};
int VAR = arr[0];
for(i = 1;i < 5; ++i)
{
if(VAR < arr[i])
VAR = arr[i];
}
cout << "Largest element in an Array is = " << VAR;
return 0;
}

    public class LFC {
public static void main(String[] args) {
int[] numArray = { 7, 9, 1, -15, 0};
int largest = numArray[0];
for (int num: numArray) {
if(largest < num)
largest = num;
}
System.out.format("Largest element in an Array is = %d", largest);
}
}

    number = [7, 9, 1, -15, 0]
largest_number = max(number);
print("Largest element in an Array is = ", largest_number)

    using System;
class LFC
{
static void Main()
{
int i       = 0;
int large   = 0;
//array declaration
int[] arr = {7, 9, 1, -15, 0};
//reading array elements 
//assigning first element to the array
large = arr[0];
//loop to compare value of large with other elements
for (i = 1; i < 5; i++)
{
//if large is smaller than other element
//assig that element to the large
if (large < arr[i])
large = arr[i];
}
//finally, we will have largest element, printing here
Console.WriteLine("Largest element in an Array = " + large);
}
}

    // Returns maximum in array 
function getMax($arr)  
{ 
$n = count($arr);  
$max = $arr[0]; 
for ($i = 1; $i < $n; $i++)  
if ($max < $arr[$i]) 
$max = $arr[$i]; 
return $max;        
} 
// Driver code 
$arr = array(7, 9, 1, -15, 0); 
echo "Largest element in an Array : ";
echo(getMax($arr)); 

    #include <stdio.h>
int main() {
int i, arr[5]={ 7, 9, 1, -15, 0};
int VAR = arr[0];
for (i = 1; i < 5; ++i) {
if (VAR < arr[i])
VAR = arr[i];
}
printf("Largest element in an Array is = %d", VAR);
return 0;
}

    Output

    Largest element in an Array is = 9
