Another way of achieving this sum?

[LeandroTheBest]

Hi everybody I'm kind of new to C++ and I dont quite get this.

So I have a code wich sums the values from an array and the it outputs the result

    while(i < 10)
    {
        sum += valor[i];

        i++;
    }

    cout << sum << endl;

So is this the only way to achieve I mean only by using += operator?

Another way is to use the C++ function accumulate():

std::cout << accumulate(valor, valor+10, 0) << '\n';

Just in case you don't realise, sum += valor[i]; is the same as sum = sum + valor[i];.

You can make a class,....wait,...it might just more complicated...
