increment and decrement operators:

Increment Operator (++):

Increment Operator increases the value by “1”. There are two types of increment operators: Pre increment operator and Post increment operator.

Post increment:

Consider the example

int X=3,Y;

Y=X++;

In the above statement ‘X’ value becomes 4 and ‘Y’ takes 3.

Pre increment:

Consider the example

int X=3,Y;

Y=++X;

In the above statement ‘X’ value becomes 4 and ‘Y’ also takes 4.

Decrement Operator (--):

Decrement Operator decreases the value by “1”. There are two types of decrement operators: Pre decrement operator and Post decrement operator.

Post decrement:

Consider the example

int X=3,Y;

Y=X--;

In the above statement ‘X’ value becomes 2 and ‘Y’ takes 3.

Pre decrement:

Consider the example

int X=3,Y;

Y=--X;

In the above statement ‘X’ value becomes 2 and ‘Y’ also takes 2.
