Write a Program to Calculate the Sum of Elements in an Array

C++// C++ Program to calculate // sum of elements in an array #include <iostream> using namespace std; int sum(int arr[], int n) { int sum = 0; for (int i = 0; i < n; i++) sum += arr[i]; return sum; } int main() { int arr[] = { 1, 23, 54, 12, 9 }; int n = sizeof(arr) / sizeof(arr[0]); cout << "Sum: " << sum(arr, n); return 0; }

Output

Sum: 99
