In computer science, a Boolean expression is an expression used in programming languages that produces a Boolean value when evaluated. A Boolean value is either true or false.
( Lol. I’m in 7th grade doing college work, so this was fun to answer! )
The pseudocode to calculate the average of the test scores until the user enters a negative input serves as a prototype of the actual program
<h3>The errors in the pseudocode</h3>
The errors in the pseudocode include:
- Inclusion of unusable segments
- Incorrect variables
- Incorrect loops
<h3>The correct pseudocode</h3>
The correct pseudocode where all errors are corrected and the unusable segments are removed is as follows:
start
Declarations
num test1
num test2
num test3
num average
output "Enter score for test 1 or a negative number to quit"
input test1
while test1 >= 0
output "Enter score for test 2"
input test2
output "Enter score for test 3"
input test3
average = (test1 + test2 + test3) / 3
output "Average is ", average
output "Enter score for test 1 or a negative number to quit"
input test1
endwhile
output "End of program"
stop

Explanation:
The attributes that are examined for the query are the attributes of the table that are mentioned in the select statement and where clause.
So according to first query we are working on all attribues of Emp table so all of the attributes of Emp table are examined.In second query we selecting all attributes of both the tables hence all attributes of both the table and same in the next query.
In fourth query though the query is not complete where clause is missing but we have eid from Emp and dname from Dept tables for sure and the attributes mentioned in where clause will also be present.
