Question

Write a program in Java to:

• Ask the user how many scores they want to enter (=> Create an array based the entered size)
• Ask the user to enter their scores in the quarter (Fill the array with the entered scores(assigned to elements)) ==>> Use a "for" loop

• Find the greatest score
• Calculate and show the average
• Show the final grade based on the average (For example A,B,C ... )
• Print the scores (the elements of the array) => Use a "for" loop

Answer 1

code:

import java.util.Scanner;

class Main {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("How many scores you want to enter : ");

int size = sc.nextInt();

int[] scores = new int[size];

System.out.println("Enter your scores");

for(int i=0;i<size;i++){

scores[i] = sc.nextInt();

}

//finding greatest score and average score

int max = -99;

double sum = 0;

for(int i=0;i<size;i++){

if(scores[i] > max){

max = scores[i];

}

sum+=scores[i];

}

System.out.printf("\nGreatest Score : %d",max);

double avg = sum/size;

System.out.printf("\nAverage Score : %.2f",avg);

char grade;

//finding grade

if(avg >= 90){

grade = 'A';

}else if(avg >= 80){

grade = 'B';

}else if(avg >= 70){

grade = 'C';

}else if(avg >= 60){

grade = 'D';

}else{

grade = 'F';

}

System.out.printf("\nYour Grade : %c",grade);

System.out.printf("\nEntered Scores : ");

for(int i=0;i<size;i++)

System.out.printf("\n%d",scores[i]);

}

}
