Question

Write a program that determines how many terms 10 students need to graduate.

Step 1. Create an algorithm (either flowchart or pseudocode) that you will use to write the program. Place the algorithm in a Word document.

Step 2. Code the program in Eclipse and ensure the following steps are accomplished.

1.  Define a two-dimension array with 10 rows and 2 columns.

2.  Prompt the user to enter the number of courses they have left to graduate (value must be between 1 and 20) and how many courses they plan to take each term (value must be between 1 and 5). If the user enters either value out of range then the user must be prompted to reenter.

3. The program must store the number of courses a student has left and how many courses they plan to take each term in a different row of the array, i.e. the first student’s number of courses and how many they plan to take each term will be stored in first row of array. The second student’s info will be in second row, and so on.

4. The program must compute the number of terms a student has remaining, and this should be an integer.   For example, if a student has 15 courses remaining and plans to take 2 a term then they need 8 terms to complete the courses.              In other words, you can have 7.5 terms because the student must attend an entire term.

Step 3. Test your program using this data.

Student 1, 8 courses and plans to take 2 a term

Student 2, 15 courses and plans to take 3 a term

Student 3, 6 courses and plans to take 1 a term

Student 4, 12 courses and plans to take 6 a term             note: error because 6 is too many courses per term

Student 4, 12 courses and plans to take 5 a term            

Student 5, 13 courses and plans to take 2 a term

Student 6, 7 courses and plans to take 3 a term

Student 7, 9 and plans to take 4 a term

Student 8, 3 and plans to take 2 a term

Student 9, 5 courses and plans to take 4 a term

Student 10, 18 courses and plans to take 3 a term

Your output should look like the sample below. Use the Snipit tool in Windows or a similar tool on the Mac to cut and paste the Eclipse Console output window into the same Word document as the algorithm in Step 1. <terminated> C8_Project (1) [Java Application] C:\Program Files Javaljre 1.8.0_131\bin\javaw.exe (Mar 26, 2019, 12:55:57 PM) Enter classes remaining and taking each term for student 1: 82 Enter classes remaining and taking each term for student 2: 153 Enter classes remaining and taking each term for student 3: 6 1 Enter classes remaining and taking each term for student 4: 126 The number of classes per term for student 4 is not valid!

Answer 1

import java.util.Scanner;

public class Main {
public static void main(String args[]) {
int arr[][] = new int[10][2];
Scanner in = new Scanner(System.in);
for (int i = 0; i < 10; i++) {
do {
System.out.print("Enter classes remaining and taking each term for student " + (i + 1) + ": ");
arr[i][0] = in.nextInt();
arr[i][1] = in.nextInt();
if(arr[i][0] < 1 || arr[i][0] > 20) {
System.out.println("The number of remaining classes for student " + (i + 1) + " is not valid");
i--;
}
if(arr[i][1] < 1 || arr[i][1] > 5) {
System.out.println("The number of classes per term for student " + (i + 1) + " is not valid");
i--;
}
} while (arr[i][0] < 1 || arr[i][0] > 20 || arr[i][1] < 1 || arr[i][1] > 5);
}

for (int i = 0; i < 10; i++) {
int terms = (int)Math.ceil(Double.valueOf(arr[i][0]) / arr[i][1]);
System.out.println("Student " + (i + 1) + " needs " + terms + " terms to graduate");
}
}
