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.
Given three numbers and the task is to find greatest among them.
Input: a = 46, b = 67, c = 21 Output: 67 Input: a = 9887, b = 4554, c = 212 Output: 9887
Approach is to consider the first number and compare it with other two numbers. Similarly, check with second and third.
Below is the required implementation:
Greatest number is 67
