Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards

, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print:
7 9 11 10
10 11 9 7

Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1.


Note: These activities may test code with different test values. This activity will perform two tests, the first with a 4-element array (int courseGrades[4]), the second with a 2-element array (int courseGrades[2]). See How to Use zyBooks.

Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message.

code:

import java.util.Scanner;

public class CourseGradePrinter {
public static void main (String [] args) {
final int NUM_VALS = 4;
int[] courseGrades = new int[NUM_VALS];
int i = 0;

courseGrades[0] = 7;
courseGrades[1] = 9;
courseGrades[2] = 11;
courseGrades[3] = 10;


return;
}
}

Answer:

Java code explained below

Explanation:

CourseGradePrinter.java

import java.util.Scanner;

public class CourseGradePrinter {

public static void main (String [] args) {

final int NUM_VALS = 4;

int[] courseGrades = new int[NUM_VALS];

int i = 0;

courseGrades[0] = 7;

courseGrades[1] = 9;

courseGrades[2] = 11;

courseGrades[3] = 10;

for(i=0; i<NUM_VALS; i++){

  System.out.print(courseGrades[i]+" ");

}

System.out.println();

for(i=NUM_VALS-1; i>=0; i--){

  System.out.print(courseGrades[i]+" ");

}

return;

}

}

Output:

7 9 11 10

10 11 9 7

Juli2301 [7.4K]

Answer:

num = int(input("enter a number:"))

print(num * 8)

Explanation:

num is just a variable could be named anything you want.

if code was like this num = input("enter a number:")

and do a print(num * 8)

we get an error because whatever the user puts in input comes out a string.

we cast int() around our input() function to convert from string to integer.

therefore: num = int(input("enter a number:"))

will allow us to do  print(num * 8)

AnnyKZ [126]

Answer:

r = 1

Explanation:

Average processing time ( p ) = 3 minutes

Average inter-arrival time ( a ) = 3 minutes

number of servers ( m ) = 3

<u>Determine the value of r </u>

r ( offered load ) = p/a

                          = 3 / 3  = 1

∴ value of r ( offered load ) = 1
