3) Write a Java application that asks the user to enter the scores in 3 different tests (test1, test2, test3) for 5 students into a 2D array of doubles. The program should calculate the average score in the 3 tests for each student, as well as the average of all students for test1, test2 and test3.
Answers
Answer:
import java.util.Scanner;
public class TestScores {
public static void main(String[] args) {
// create a 2D array of doubles to hold the test scores
double[][] scores = new double[5][3];
// use a Scanner to get input from the user
Scanner input = new Scanner(System.in);
// loop through each student and each test to get the scores
for (int i = 0; i < 5; i++) {
for (int j = 0; j < 3; j++) {
System.out.print("Enter score for student " + (i+1) + " on test " + (j+1) + ": ");
scores[i][j] = input.nextDouble();
}
}
// calculate the average score for each student and print it out
for (int i = 0; i < 5; i++) {
double totalScore = 0;
for (int j = 0; j < 3; j++) {
totalScore += scores[i][j];
}
double averageScore = totalScore / 3;
System.out.println("Average score for student " + (i+1) + ": " + averageScore);
}
// calculate the average score for each test and print it out
for (int j = 0; j < 3; j++) {
double totalScore = 0;
for (int i = 0; i < 5; i++) {
totalScore += scores[i][j];
}
double averageScore = totalScore / 5;
System.out.println("Average score for test " + (j+1) + ": " + averageScore);
}
}
}
Explanation:
Here's how the program works:
It creates a 2D array of doubles with 5 rows (one for each student) and 3 columns (one for each test).
It uses a Scanner to get input from the user for each test score for each student. It prompts the user with the student number and test number for each score.
It loops through each student and calculates the average score for each student by adding up all the test scores for that student and dividing by 3 (the number of tests).
It prints out the average score for each student.
It loops through each test and calculates the average score for each test by adding up all the test scores for that test and dividing by 5 (the number of students).
It prints out the average score for each test.
Note that this program assumes that the user will input valid numbers for the test scores. If the user inputs non-numeric data or numbers outside the expected range, the program will throw an exception. To handle this, you could add input validation code to ensure that the user inputs valid data.

A processor operates at a clock rate of 1.6 GHz yet has a varying CPI for different instruction types. A given program has 400 ALU instructions which take the processor 7 cycles complete each instruction. It has 300 memory instructions that take 12 cycles to cycles to complete each instruction. It also has 90 branching operations that take 21 cycles to cycles to complete each instruction. How long does it take to execute this program
Answers
Answer:
0.0051825 ms
Explanation:
From the given information:
The clock time is = \(\dfrac{1}{clok \ rate}\)
\(=\dfrac{1}{6} Ghz\)
\(=\dfrac{1}{6}\times 10^9\)
To milliseconds, we have;
= 0.000000625 ms
However, the execution time is the sum total of all instruction types multiplied by the ratio of cycles taken per instruction and cycle time.
Mathematically;
Execution time is: \(\Bigg[Sum \ of \ all \Big(instruction \ type \times \dfrac{cycles taken }{instruction} \Big) \Bigg] \times cycle \ time\)
Recall that:
the cycles taken according to the ALU = 400 × 7 =2800
cycles required according to the memory instructions = 300 × 12 = 3600
cycles for branching = 90×21 = 1890
THUS;
Total cycles = 2800 + 3600 + 1890
= 8290 cycles
Finally, execution time = 8290 cycles × 0.000000625 ms
= 0.0051825 ms

Write a program that tells what coins to give out for any amount of change from 1 cent to 99 cents. For example, if the amount is 86 cents, the output would be something like the following:
86 cents can be given as 3 quarters 1 dime and 1 penny
Use coin denominations of 25 cents (quarters), 10 cents (dimes), and 1 cent (pennies). Do not use nickel and half dollar coins. Your program will use the following function (among others):
void computeCoin(int coinValue, int& number, int& amountLeft);
For example, suppose the value of the variable amountleft is 86. Then, after the following call, the value of number will be 3 and the value of amountLeft will be 11 (because if oyu take three quarters from 86cents, that leaves 11 cents):
computecoins (25, number, amountLeft);
Include a loop that lets the user repeat this computation for new input values until the suer says he or she wants to end the program (Hint: use integer division and the % operator to implement this function.)
