- * Increment and decrement operators can be used in two ways,
- * postfix (as given in above example) and prefix.
- *
- * In normal use, both form behaves the same way. However, when they
- * are part of expression, there is difference between these
- * two forms.
- *
- * If prefix form is used, operand is incremented or decremented
- * before substituting its value.
- *
- * On the other hand, if postfix form is used,
- * operand's old value is used to evaluate the expression.

- * Simple example would be,
