Check whether a given number is even or odd in PL/SQL
Prerequisite – PL/SQL introduction
In PL/SQL code groups of commands are arranged within a block. A block group related declarations or statements. In declare part, we declare variables and between begin and end part, we perform the operations.
Examples:
Input: 2 Output: even Input: 5 Output: odd
The approach is to divide the given number by 2 and if the remainder is 0 then the given number is even else odd.
Below is the required implementation:
DECLARE -- Declare variable n, s, r, len -- and m of datatype number n NUMBER := 1634; r NUMBER; BEGIN -- Calculating modulo r := MOD(n, 2); IF r = 0 THEN dbms_output.Put_line( 'Even' ); ELSE dbms_output.Put_line( 'Odd' ); END IF; END ; --End program |
Output:
Even
