+= operator?
I have long fogoton the += -= and all those operators. I am looking at a 2d array and came across this:

for (int i=0; i<maxrow; i++)
{
sum += array2d[0][i];

etc. etc.
}

does the += equal all the i's together?

EDIT:: Did i just call them operators?

sum += num;

is equivalent to:

sum = sum + num;
