Increment and decrement operators are unary operators that add or subtract one from their operand, respectively. They are commonly implemented in imperative programming languages. C-like languages feature two versions (pre- and post-) of each operator with slightly different semantics.

The difference between the two increment operators is this: ++i is called the preincrement operator. It means "increment i, then give me the new value." i++ is called the postincrement operator. It means "tell me the current value of i, then increment it afterwards*."
