Question

Explanation of Increment(++) and Decrement(--) Operator
Can anyone explain the concept of Increment(++) and Decrement(--) operator?

Answer 1

Increment and decrement operators are used to add or subtract 1 from the current value of oprand.

++ increment
-- decrement

Increment and Decrement operators can be prefix or postfix. In the prefix style the value of oprand is changed before the result of expression and in the postfix style the variable is modified after result.

For example.
a = 9;
b = a++ + 5; /* a=10 b=14 */
a = 3;
b = ++a + 6; /* a=10 b=15 */

Answer 2

Increment operator:- The operator which increase the value of a variable by one called increment operator.

Ex:-

a=1;

++a=2

Decrement operator:-The operator which decrease the value of a variable by one called decrement operator.

Ex:-

a=1;

--a=0
