Description

Get an array as input from the user and then find the smallest and largest element in the array.

Input

Enter the size of array: 5

Enter the elements:  10 20 5 40 30

Output

Smallest Number: 5

Largest Number: 40

 

C Program

#include<stdio.h>

void check(int arr[], int n)

{

    int small, large;

    small = large = arr[0];

    for(int i = 1; i < n ;i++){

        if(arr[i] < small) small = arr[i];

        if(arr[i] > large)

            large = arr[i];

    }

    printf("Smallest Number: %d\n",small);

    printf("Largest Number: %d", large);

}

int main()

{

    int n;

    printf("Enter the size of array: ");

    scanf("%d",&n);

    int arr[n];

    printf("Enter the elements of array: ");

    for(int i=0;i<n;i++)

    scanf("%d",&arr[i]);

    check(arr, n);

    return 0;

}

 

C++ Program

#include<iostream>

using namespace std;

void check(int arr[], int n)

{

    int small, large;

    small = large = arr[0];

    for(int i = 1; i < n ;i++){

        if(arr[i] < small) small = arr[i];

        if(arr[i] > large)

            large = arr[i];

    }

    cout<<"Smallest Number: "<<small<<"\n";

    cout<<"Largest Number: "<<large<<"\n";

}

int main()

{

    int n;

    cout<<"Enter the size of array: ";

    cin>>n;

    int arr[n];

    cout<<"Enter the elements of array: ";

    for(int i=0;i<n;i++)

    cin>>arr[i];

    check(arr, n);

    return 0;

}

 

Java Program

import java.util.Scanner;

public class Main

{

   public static void main(String args[])

   {

 

       int n;

    Scanner sc = new Scanner(System.in);

    System.out.println("Enter the size of the array: ");

    n = sc.nextInt();

    int[]arr = new int[n];

    System.out.println("Enter the array elements: ");

    for(int i = 0; i < n; i++)

    {

        arr[i] = sc.nextInt();

    }

       int large = arr[0], small=arr[0];

 

       for(int i=0; i<arr.length; i++)

       {

           if(small > arr[i])

              small = arr[i];

           if(large < arr[i])

              large = arr[i];

 

       }

 

       System.out.println("Smallest Number: "+small);

       System.out.println("Largest Number: "+large);

   }

}

 

Python Program

n = int(input("Enter size of array: "))

arr = []

print("Enter array elements: ")

for i in range(0,n):

                temp = int(input())

                arr.append(temp)

small = arr[0]

large = arr[0]

for i in range(len(arr)):

  if arr[i] < small:

    small = arr[i]

  if arr[i] > large:

    large = arr[i]

print ("Smallest Number: ",small)

print ("Largest Number: ",large)
