What is a Post / Pre-Increment and Decrement?

Increment operators are used to increase the value by one while decrement works opposite and decreases the value by one.

Pre-increment (++i) : Before assigning the value to the variable, the value is incremented by one.
Post-increment (i++) : After assigning the value to the variable, the value is incremented

Pre-decrement (--i) : Before assigning the value to the variable, the value is decremented by one.
Post-decrement (i--) : After assigning the value to the variable, the value is decremented by one.

Example:

The following is the syntax of pre and post increment:
++variable_name; // Pre-increment
variable_name++; // Post-increment
--variable_name; // Pre-decrement
variable_name--; // Post-decrement
