Write a program to find sum of element in array.

Given a integer array we have to find the sum of element in an array. .

Example:

input:arr[]={1,2,3,4,5}

output:15

Logic:

step 1- iterate the whole array and initialise sum variable.
step 2-add the value to the sum variable

Code-

#include<bits/stdc++.h>
using namespace std;

int main()
{
	int arr[] = { 22, 85, 11, 90, 84, 12 };
	int n = sizeof(arr) / sizeof(arr[0]);
	int sum=0;
for(int i=0;i<n;i++)
{
    sum+=arr[i];
}
cout<<sum<<endl;
	
	
}

Output:

304

Time complexity:0(N)

Space Complexity:O(1)
