Problem adding all the elements in an array using a ranged-based for loop

#include <iostream>
using namespace std;
int main() {  

    double numbers[] = {7, 5, 6, 12, 35, 27};
    double average, count, sum = 0;

    cout << "The numbers are: ";

    for(const double &n : numbers) {
        cout << n << " ";
    }

    cout << endl;

    cout << "The sum is: ";

    for(const double &n : numbers) {
        sum += n;
        cout << sum;
    }

    cout << endl;
    return 0;

}

The output of sum should be 92 for adding all the elements in the array and i don’t know where i went wrong but this what keeps appearing to me instead:

The sum is 71218306592

>Solution :

Split this output

71218306592

like

7 12 18 30 65 92

using this statement in the last range-based for loop

cout << sum << ' ';

Or place this statement

cout << sum;

outside the last range-based for loop.

for(const double &n : numbers) {
    sum += n;
}
cout << sum;

Pay attention to that neither variable average nor count is used in your program.
