Answer:
Explanation:
There are various questions that you can ask in this scenario, such as
What grading policies are being implemented?
How many student grades are being calculated by the program?
What is the requirements for a student to pass?
All of these questions would allow you to get an idea of how extensive the code may be and its complexity. Once you know this you would look at the code revolving around actually looping through the data and doing the necessary calculations. You can then determine how to manipulate the code and make it much more efficient.
You would also need to know how the student data is being saved, which will help determine if it is the best data structure for saving this type of data or if it can be replaced in order to maintain the data secure while increasing the speed of the program. Mainly since this information needs to be continuously used from the data structure.
Answer:
Hi there! The question is checking your knowledge on Pseudocode. Pseudocode is a high level solution written in plain English to outline the steps needed for the program to work correctly. An implementation for the different parts of the question is written below.
Explanation:
1. Determine the area of a triangle
declare formula for area calculation of triangle as ½ * (base * height)
validate input parameters “base” and “height”
apply formula and return result
2. Compute the interest earned Prompt user for input 2
declare formula for interest calculation as annual interest rate * term * starting account balance
validate input parameters “interest_rate” and “starting_account_balance ”
apply formula and return result as final balance at the end of the year as the interest earned + starting balance.
3. Determine the flying time between two cities given the mileage M between them and the average speed of the airplane.
declare formula for time calculation of triangle as time = distance / speed
validate input parameters for mileage “M” and speed “S”
apply formula and return result
The command is : <span>rm [Aa]*[Zz] </span>
Answer:
A primary key is a special relational database table column (or combination of columns) designated to uniquely identify each table record. A primary key is used as a unique identifier to quickly parse data within the table. A table cannot have more than one primary key.
Primary Key.
Candidate Key.
Alternate Key.
Super Key.
Composite Key.
Foreign Key.
Unique Key.
In the relational model of databases, a primary key is a specific choice of a minimal set of attributes that uniquely specify a tuple in a relation. Informally, a primary key is "which attributes identify a record," and in simple cases constitute a single attribute: a unique ID.
