Create a method called letterGrade that will pass the student's average grade as a parameter and return a letter grade (char). Once passed, use an if..else if structure to determine whether the student has an A, B, C, D, or F. Return that letter grade. Use the standard grade scale: 90-100 (A), 80-89 (B), 70-79 (C), 60-69 (D), 0-59 (F).
Answer:
The method in Java is as follows:
public static char letterGrade(int average){
char grade =' ';
if(average>= 90 && average <=100){ grade ='A'; }
else if(average>= 80 && average <=89){ grade ='B'; }
else if(average>= 70 && average <=79){ grade ='C'; }
else if(average>= 60 && average <=69){ grade ='D'; }
else if(average>= 0 && average <=59){ grade ='F'; }
return grade;
}
Explanation:
This defines the method
public static char letterGrade(int average){
This initializes the grade to a blank
char grade =' ';
If average is between 90 and 100 (inclusive), grade is A
if(average>= 90 && average <=100){ grade ='A'; }
If average is between 80 and 89 (inclusive), grade is B
else if(average>= 80 && average <=89){ grade ='B'; }
If average is between 70 and 79 (inclusive), grade is C
else if(average>= 70 && average <=79){ grade ='C'; }
If average is between 60 and 69 (inclusive), grade is D
else if(average>= 60 && average <=69){ grade ='D'; }
If average is between 0 and 59 (inclusive), grade is F
else if(average>= 0 && average <=59){ grade ='F'; }
This returns the grade
return grade;

Write a program named prices.c that repeatedly asks users to enter the price of an item until they enter zero. Prices less than zero will be ignored. The program will then print the number of items purchased, the subtotal of the prices, the sales tax charged (at a rate of 7.5%), and the grand total.
Answer:
Explanation:
The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int quantity = 0;
double subtotal = 0;
double tax, grandTotal;
while (true) {
System.out.println("Enter a price: ");
double price = in.nextDouble();
if (price == 0) {
break;
} else if (price > 0) {
quantity += 1;
subtotal += price;
}
}
tax = subtotal * 0.075;
grandTotal = subtotal + tax;
System.out.println("Quantity: $" + quantity);
System.out.println("Subtotal: $" + subtotal);
System.out.println("Tax: $" + tax);
System.out.println("GrandTotal: $" + grandTotal);

1. Design pseudocode for a program that will permit a user to store exactly 75 numbers in an array. Create an array big enough to hold the numbers and store each number in the array as it's entered. Be sure to PROMPT the user for each number before it's entered. You do not need to initialize the array. HINTS: Make sure you use a named constant when you declare the array (the number inside the brackets should be a named constant that you declared before the array declaration.) Use a for loop (or while loop if you'd like) to get each number from the user. The module has an example of pseudocode very similar to this problem. You're free to use this pseudocode as you create your program. 2. Identify three advantages of arrays. For each advantage, write at least one complete sentence explaining why the advantage you listed is an advantage. More detail is better. You may use outside resources but be sure to CITE those resources using APA format.
Answer:
Question 1: The pseudocode is as follows:
int n = 70;
int intArray[n];
for(int i = 0; i< n; i++){
print("Input "+(i+1)+": ")
input intArray[i];
}
Question 2: Advantages of array
Indexing in arrays in easyIt can be used to store multiple values of the same typeIt can be used for 2 dimensional inputsExplanation:
Question 1
This declares and initializes the length of the array
int n = 70;
This declares the array
int intArray[n];
This iterates through the length of the array
for(int i = 0; i< n; i++){
This prompts the user for inputs
print("Input "+(i+1)+": ")
This gets input for each element of the array
input intArray[i];
}
Question 2
Indexing: Elements of the array can easily be accessed through the index of the element.
For instance, an element at index 2 of array intArray can be accessed using: intArray[2]
Multiple Values: This is illustrated in question 1 above where we used 1 array to collect input for 70 values.
2 dimensional inputs: Literally, this means that array can be used to represent matrices (that has rows and columns).
An illustration is:
intArray[2][2] = {[0,1],[3,5]}
The above array has 2 rows, 2 columns and 4 elements in total.
