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:
- import java.util.Scanner;
- public class Main {
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Please enter two characters: ");
- String inputStr = input.nextLine();
-
- if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
- System.out.println("Biology");
- }
- else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
- System.out.println("Computer Science");
- }
- else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
- {
- System.out.println("Information Technology and Systems");
- }
- else{
- System.out.println("Invalid major");
- }
-
- int num = Character.getNumericValue(inputStr.charAt(1));
-
- if(num >= 1 && num <= 4){
- switch (num){
- case 1:
- System.out.println("freshman");
- break;
- case 2:
- System.out.println("sophomore");
- break;
- case 3:
- System.out.println("junior");
- break;
- case 4:
- System.out.println("senior");
- break;
- }
-
- }
- else{
- System.out.println("Invalid year status");
- }
-
- }
-
- }
Explanation:
The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.
The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.
Answer:
The input interprets the data while it is in RAM.
Explanation:
Ctrl + v pastes copied text, ctrl + p brings up a print menu, ctrl + x cuts and copies highlighted text, while ctrl + c copies the highlighted text.

5. B
Explanation:
1. To check the integrity of your hard disk and fix various file system errors, the Windows utility which should be implemented is Check disk (Chkdsk). This utility is always used with the command line interface (CLI) with the command "chkdsk."
2. An event or action took place and it caused damage to data, hardware, software and processing capability of the computer. From the statement given, security risks are being described. Any event or action that is capable of causing a problem to a computer system is considered to be a security risk and should be prevented through the use of an appropriate utility software.
3. Virus is a software program that can infect, damage and disrupts the whole computer system.
4. To protect the whole computer system, the software utility which is needed is an Anti-virus.
5. To avoid losing valuable data to your computer, the most important thing to do is to regularly back-up your files.
