Write a Program in C++ That Compute The Sum of The Elements of An Array

// Compute the sum of the elements of an array.

#include <iostream>

#include <array>

using namespace std;

int main()

{

   const size_t arraySize = 4; // specifies size of array

   array< int, arraySize > a = { 10, 20, 30, 40 };

   int total = 0;

   // sum contents of array a

   for ( size_t i = 0; i < a.size(); ++i )

      total += a[ i ];

   

   cout << "Total of array elements: " << total << endl;

} // end main
