{

    printf("Enter the size of the array:");
    int size;
    scanf("%d",&size);
    int arr[size],i=0,max=INT_MIN,j=0;
    printf("Enter the Element of the array:\n");
     while(j<size)
    {
        scanf("%d",&arr[j]);
        j++;
    }
    while(i<size)
    {
        if(arr[i]>=max)
        max=arr[i];
        i++;

    }
    printf("The largest element of array: %d",max);
}

Input/Output:

Enter the size of the array:6
Enter the Element of the array:
30
25
87
5
2

Program in C++

Here is the source code of the C++ Program to Find the largest element in the array.

Code:

#include<iostream>
#include<climits>
using namespace std;
int main()
{

    cout<<"Enter the size of the array:";
    int size;
    cin>>size;
    int arr[size],i=0,max=INT_MIN,j=0;
     cout<<"Enter the Element of the array:\n";
     while(j<size)
    {
        cin>>arr[j];
        j++;
    }
    while(i<size)
    {
        if(arr[i]>=max)
        max=arr[i];
        i++;

    }
    cout<<"The largest element of array: "<<max;
}

Program in Java

Here is the source code of the Java Program to Find the largest element in the array.

Code:

import java.util.Scanner;
public class p8 {

public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("Enter the size of the array:");
    int size;
    size=sc.nextInt();
    int arr[ ]=new int[size];
int i=0,max=Integer.MIN_VALUE,j=0;
System.out.println("Enter the Element of the array:");
     while(j<size)
    {
        arr[j]=sc.nextInt();
        j++;

    }
    while(i<size)
    {
        if(arr[i]>=max)
        max=arr[i];
        i++;
    }
    System.out.println("The largest element of array: "+max);
    sc.close();
}
}

Input/Output:

Enter the size of the array:
3
Enter the Element of the array:
10
305
987
The largest element of array: 987

Program in Python

Here is the source code of the Python Program to Find the largest element in the array.

Code:

import sys
arr=[]
size = int(input("Enter the size of the array: "))
print("Enter the Element of the array:")
for i in range(0,size):
    num = int(input())
    arr.append(num)
max=-sys.maxsize-1
for j in range(0,size):
    if (arr[j] >= max):
        max = arr[j]
print("The largest element of array: ",max)
