Given an array of integers, find sum of its elements.
Examples :
Input : arr[] = {1, 2, 3}
Output : 6
1 + 2 + 3 = 6
Input : arr[] = {15, 12, 13, 10}
Output : 50
C/C++
/* CPP Program to find sum of elements in a given array */#include <bits/stdc++.h> // function to return sum of elements // in an array of size n int sum(int arr[], int n) { int sum = 0; // initialize sum // Iterate through all elements // and add them to sum for (int i = 0; i < n; i++) sum += arr[i]; return sum; } int main() { int arr[] = {12, 3, 4, 15}; int n = sizeof(arr) / sizeof(arr[0]); printf("Sum of given array is %d", sum(arr, n)); return 0; } |
