Answer:

1.) 25 ; 15 ; 15

2.) 50 ; 15 ; 50

Explanation:

In the first function written :

The variable val was initially decaled or assigned a value of 25 and that was what was printed first.

However, after the example function was written, the val variable was finally assiagned a value of 15 within the function. However, it was also declared that the global variable takes uonthe val value. Hence, the val variable initially assigned a value, of 25 changes to 15 globally.

For the second code :

From the top:

Val was assigned a value of 50 ;

Hence,

print(val) gives an output of 50

Within the function definition which prints the value of val that is assigned a value of 25 within the function.

Since tbe global variable isnt reset.

Printing Val again outputs 50;since ito is outside the function.

If a database is not maintained or if incorrect data is entered into the database, serious problems can occur. What problems cou

Archy [21]

Database is maintained by keeping only relevant data and updating existing data in a timely manner.

This is achieved by issuing proper insert, update and delete operations.

Incorrect data leads to incomplete information. Databases which hold transaction details, any inaccuracies lead to misinformation to its users.

Both the above lead to serious issues in data maintenance and prove the database ineffective. This indicates manhandling of the database.

No maintenance

Database is maintained when only relevant information is present. Irrelevant information includes information like information of past students, old information of current students, etc.

For students who have completed their courses and left, the database should be updated by removing data of such students.

Also, for newly enrolled students, their enrolment should reflect in the official records.

In case of changes in any of the student information, timely update operations should be performed to keep only current data in the database.

All these operations should be done timely in order to avoid any discrepancies in the real data and updated data in the system.

Incorrect data

In situations where incorrect data is input in the student database, incorrect data will be recorded for that particular student. Incorrect data can be related to ssn, name, address, course details and fees payment.

In case of incorrect transaction details like fees payment, this incorrect data will reflect in the student record as well as will affect the overall earnings of the school.

For enrolled students, correct enrollment details regarding the course and classroom should be recorded. Any error in this data will cause the student inconvenience and the respective student will be at loss.

Also, taking advantage of this situation, any outsider acting as an enrolled student, can gain access to the school.

This leads to mismatch of information and can lead to fraud situations against the educational institute.

write a java program that prompts the user to enter scores (each number an integer from 0 to 10) and prints the following output

Vladimir [108]

Answer:

Explanation:

The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int count = 0;

int highest, lowest;

ArrayList<Integer> myArr = new ArrayList<>();

while (true) {

System.out.println("Enter a number [0-10] or -1 to exit");

int num = in.nextInt();

if (num != -1) {

if ((num >= 0) && (num <= 10)) {

count+= 1;

myArr.add(num);

} else {

System.out.println("Wrong Value");

}

} else {

break;

}

if (myArr.size() > 3) {

highest = myArr.get(0);

lowest = myArr.get(0);

for (int x: myArr) {

if (x > highest) {

highest = x;

}

if (x < lowest) {

lowest = x;

}

System.out.println("Number of Elements: " + count);

System.out.println("Highest: " + highest);

System.out.println("Lowest : " + lowest);

} else {

System.out.println("Number of Elements: " + count);

System.out.println("No Highest or Lowest Elements");

}
