The Data Manipulation Language statements are
Declare a number := 5; b number := null; c number := 10; Begin if a > b AND a < c then a := c * a; end if; End; What will be the value of 'a' after execution?
To determine the value of 'a' after execution, let's go through the code step by step:
Declare the variables:
- a = 5
- b = null
- c = 10
Evaluate the condition:
a > b AND a < c
a is not null and satisfies both conditions (
5 > null and
5 < 10), the condition evaluates to true.
- Execute the code within the if statement:
a := c * a
Update the value of
10 * 5 = 50.
Therefore, the value of 'a' after execution will be 50.
The correct answer is A) 50.
