Question #cac52

Answer 1

`"sum + = 47"`

Explanation:

As you know, the C++ statement

`"sum" = "sum" + 47`

is equivalent to

`"the new value of sum" = "the old value of sum" + 47`

In other words, the variable that is added to the left of the `=` sign is being assigned the value that is added to the right of the `=` sign.

In this case, for every iteration, the value of the variable `"sum"` increases by `47`.

Now, you can write this using a single arithmetic assignment operator like this

`"sum + = 47"`

This is equivalent to saying that with every iteration, the variable that is added to the left increase by the value added to the right of the `=` sign.

In this notation, the fact that the value assigned to the variable is increasing by `47` is being added to the left of the `=` sign.
