HackerRank Simple Array Sum Solution in C++

Given an array of integers, find the sum of its elements.

For example, if the array ar = [1, 2, 3] 1 + 2 + 3 = 6 so return 6. 

Function Description

Complete the simple Array Sum function with the following parameter(s):

• ar[n] an array of integers

Returns

• int: the sum of the array elements

Input Format

The first line contains an integer, n. denoting the size of the array.

The second line contains n space-separated integers representing the array's elements.

Constraints

0 < n, ar[i] <= 1000

Sample Input

STDIN           Function
-----           --------
6               ar[] size n = 6
1 2 3 4 10 11   ar = [1, 2, 3, 4, 10, 11]

Sample Output

31

Explanation

Print the sum of the array's elements: 1 + 2 + 3 + 4 + 10 + 11 = 31
