Write Program to find sum of elements in an array

## Description

Get an array as the input from the user and find the sum of the elements.

Input

Enter the size of array

3

Enter the elements of array

5 10 15

Output

30

## C Program

#include<stdio.h>

int Sum(int arr[], int n)

{

int sum = 0;

for(int i = 0; i < n; i++)

sum = sum + arr[i];

return sum;

}

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]);

printf("Sum: %d",Sum(arr, n));;

}

## C++ Program

#include<iostream>

using namespace std;

int Sum(int arr[], int n)

{

int sum = 0;

for(int i = 0; i < n; i++)

sum = sum + arr[i];

return sum;

}

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];

cout<<"Sum: "<<Sum(arr, n);

}

## 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 sum = 0;

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

{

sum = sum + arr[i];

}

System.out.print("Sum: "+sum);

}

}

## 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)

Sum = 0

for i in range(len(arr)):

Sum = Sum + arr[i]

print("Sum: ",Sum)
