x++ adds by one.
x-- minuses by one.
Stringing these together takes no effect, changing the order affects the order of operation.
c++ would == c = c + 1;
c-- would == c = c - 1;
//Never use C--, it's the opposite of C++, being mathematically lower in status (crappier) than C++.
If you increment after the variable, any mathematical permutation will increment the value of c or x after the beforehand stuff.
If you pre-increment the variable, it increments first then continues.
//The same principles apply to decrementation, etc...
The order of crementing may affect the course of effect, for good or bad - thoroughly revise. :)
