Question

Describe the difference between increment and decrement operators.

Answer 1

increment (++)adds the value one
decrement(--) substrates the value one

Answer 2

The difference between increment and decrement operators are very simple. Increment operators increase the value of the variable by a particular number by which it is increased.  

On the other hand decrement operators decrease the value of the variable by a particular number by which it was decreased, For example, i+2, i-2.
