06 May 2024

Description about the Program to find number of even and odd elements in an array

Get an array as input from the user and then count the number of even and odd elements present in the array.

Input

Enter size of array

4

Enter the elements:

1 3 4 5

Output

Number of even elements: 1

Number of odd elements: 3

 

C Program to find number of even and odd elements in an array

#include<stdio.h>

int main(){

    int n;

   int arr[n];

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

   scanf("%d",&n);

   printf("Enter the array elements: ");

   for(int i=0;i<n;i++)

   scanf("%d",&arr[i]);

   int even=0, odd=0;

   for(int i=0; i<n; i++){

     if(arr[i]%2==0)

       even++;

     else

       odd++;

   }

   printf("Number of even elements: %d \nNumber of odd elements: %d", even, odd);

}

 

C++ Program to find number of even and odd elements in an array

#include<iostream>

using namespace std;

int main(){

    int n;

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

   cin>>n;

   int arr[n];

   cout<<"Enter the array elements: ";

   for(int i=0;i<n;i++)

   cin>>arr[i];

   int even=0, odd=0;

   for(int i=0; i<n; i++){

     if(arr[i]%2==0)

       even++;

     else

       odd++;

   }

   cout<<"Number of even elements: "<<even<< "\nNumber of odd elements: "<<odd;

}

 

Java Program to find number of even and odd elements in an array

import java.util.Scanner;

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 even = 0, odd = 0;

     for(int i=0; i<n; i++){

         if((arr[i] % 2 )== 0)

           even += 1;

 

         else

           odd += 1;

     }

     System.out.println("Number of even elements: "+ even);

     System.out.println("Number of odd elements: "+ odd);

  }

}

 

Python Program to find number of even and odd elements in an array

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

arr = []

print("Enter array elements: ")

for i in range(0,n):

                temp = int(input())

                arr.append(temp)

even = 0

odd = 0

for i in range(0, n):

   if arr[i]%2==0 :

    even += 1

   else:

    odd += 1

print("Number of even elements: ",even )

print("Number of odd elements: ",odd)
