++i add 1 to i
--j subtract 1 from j
These correspond to the slightly longer i += 1 and j -= 1, respectively, and also to the fully ``longhand'' forms i = i + 1 and j = j - 1.
The ++ and -- operators apply to one operand (they're unary operators). The expression ++i adds 1 to i, and stores the incremented result back in i. This means that these operators don't just compute new values; they also modify the value of some variable. (They share this property--modifying some variable--with the assignment operators; we can say that these operators all have side effects. That is, they have some effect, on the side, other than just computing a new value.)
The incremented (or decremented) result is also made available to the rest of the expression, so an expression like
k = 2 * ++i
means ``add one to i, store the result back in i, multiply it by 2, and store that result in k.'' (This is a pretty meaningless expression; our actual uses of ++ later will make more sense.)
Both the ++ and -- operators have an unusual property: they can be used in two ways, depending on whether they are written to the left or the right of the variable they're operating on. In either case, they increment or decrement the variable they're operating on; the difference concerns whether it's the old or the new value that's ``returned'' to the surrounding expression. The prefix form ++i increments i and returns the incremented value. The postfix form i++ increments i, but returns the prior, non-incremented value. Rewriting our previous example slightly, the expression
k = 2 * i++
means ``take i's old value and multiply it by 2, increment i, store the result of the multiplication in k.''
The distinction between the prefix and postfix forms of ++ and -- will probably seem strained at first, but it will make more sense once we begin using these operators in more realistic situations.
1++
or
(2+3)++
The ++ operator doesn't just mean ``add one'';
it means ``add one to a variable'' or ``make a variable's value one more than it was before.''
But (1+2) is not a variable, it's an expression;
so there's no place for ++ to store the incremented result.
Another unfortunate example is
i = i++;
which some confused programmers sometimes write, presumably because they want to be extra sure that i is incremented by 1. But i++ all by itself is sufficient to increment i by 1; the extra (explicit) assignment to i is unnecessary and in fact counterproductive, meaningless, and incorrect.
If you want to increment i (that is, add one to it, and store the result back in i), either use
i = i + 1;
or
i += 1;
or
++i;
or
i++;
Don't try to use some bizarre combination.
Did it matter whether we used ++i or i++ in this last example? Remember, the difference between the two forms is what value (either the old or the new) is passed on to the surrounding expression. If there is no surrounding expression, if the ++i or i++ appears all by itself, to increment i and do nothing else, you can use either form; it makes no difference.
for(i = 0; i < 10; ++i)
printf("%d\n", i);
and
for(i = 0; i < 10; i++)
printf("%d\n", i);
will behave exactly the same way and produce exactly the same results. (In real code, postfix increment is probably more common, though prefix definitely has its uses, too.)
