C Program for Increment and Decrement Opereators

Increment operator:

++varaiable -> first increments value of a by 1 and used incremented value of a in the current statement.

varaiable++ -> first value of a is used in the current statement and increments value of a by 1.

Decrement operator:

--varaiable -> first increments value of a by 1 and used decremented value of a in the current statement.

varaiable-- -> first value of a is used in the current statement and decrements value of a by 1.
