Answer:
CREATE FUNCTION exam_eligible_students
RETURN NUMBER AS
num_students NUMBER(15);
BEGIN
SELECT COUNT(STUDENT_ID)
INTO num_students
FROM STUDENT_ATTENDANCE
WHERE ELIGIBILITY_FOR_EXAMS = 'Y';
RETURN (num_students);
END;
Explanation:
exam_eligible_students is a made of name for the FUNCTION to be called.
num_students is a made up name for the RETURN to be called. The RETURN name is referenced in the INTO statement and as the name of the the return in the RETURN line in ().
Answer:
The answer to this question is given below in the explanation section.
Explanation:
An algorithm is the list of a finite set of instructions and rules that a computer needs to do to complete a task in order to solve a problem.
In short, an algorithm is a series of instructions that are implemented step by step to solve a problem. For example, you could consider a pizza recipe an algorithm for making a pizza in an everyday life routine. But when you are talking about using algorithms in computation and in mathematics. It means that solving a problem using a series of steps step by step.
For example, your everyday tasks aligned on a google calendar and remind you about your tasks using the alarm, etc- how to implement this using set of instructions and rules- is an algorithm.
Solving a quadratic equation is another example of an algorithm.
Binary search, array sorting are an example of an algorithm in computation. Because these algorithms based on the execution of step-by-step instruction to solve a problem such as sorting a list of numbers etc.
Simple waveform - something like a sine wave. Very pure sound like you used to get on the tv when that girl was sitting with the toys in the middle of the night. Complex waveform is like speech etc
The difference between the new and open commands on the file menu are quite simple. The new command creates a brand new file, while the open command opens a file that already exists or has been created.
