    Default The += assignment operator?

    Hey guys I have a quick question. Could anyone explain to me what the += does and how it works? I have seen it in different examples that use arrays but I still don't get what it's supposed to do.

    Here is an example I saw in my book:

    a[5] = 10;
    i = 5;
    a[i++] += 2;

    Default Re: The += assignment operator?

    These two are functionally equivalent:

    a += expr

    a = a + (expr)

    Same goes for all the other blah-equals operators (-=, *=, ...etc).
