Increment or Decrement numbers in apex

In Apex, you can use the ++ or -- operators to increase or decrease a variable's value by one. The position of the operator (before or after the variable) determines when the value is updated during execution.

The following code snippet shows how to increment a variable value before and after it is used.

In the above example:

The variables count, currentCount, items, newItems are Integer variables.
The operator ++ on count variable, increment the value of count by one before it is assgined to currentCount.
The operator ++ on items variable, increment the value of count by one after it is assgined to newItems.
