Write a C++ program that opens and reads file question2.txt. File question1.txt has 3 students and 3 grades of each. You program should read values from file and assign values to 4 variables: (string) name, (double) grade1, (double) grade2, (double) grade3. Then, it should calculate the average grade of each student with the precision of 2 (use setprecision(n) function from header file) and find maximum and minimum grade in the class. Finally, you should have a report on both: • console screen • Output file named output2.txt in the following output format: Max Grade max Min Grade min Adam ave_grade John ave_grade Bill ave_grade

Write a program that accepts any number of homework scores ranging in value from 0 through

the user for a new value if they enter an alphabetic character. Store the values in an array.
Calculate the average excluding the lowest and highest scores. Display the average as well as the
highest and lowest scores that were discarded.
Answers
Answer:
This program is written in Java programming language.
It uses an array to store scores of each test.
And it also validates user input to allow only integers 0 to 10,
Because the program says the average should be calculated by excluding the highest and lowest scores, the average is calculated as follows;
Average = (Sum of all scores - highest - lowest)/(Total number of tests - 2).
The program is as follows (Take note of the comments; they serve as explanation)
import java.util.*;
public class CalcAvg

public static void main(String [] args)

Scanner inputt = new Scanner(System.in);
// Declare number of test as integer

{
try
{
Scanner input = new Scanner(System.in);
System.out.print("Enter number of test (1 - 10): ");
numTest = input.nextInt();
check = false;
if(numTest>10 || numTest<0)
check = true;
}
catch(Exception e)
{
check = true;
}
}
while(check);
int [] tests = new int[numTest];
//Accept Input
for(int i =0;i<numTest;i++)
{
System.out.print("Enter Test Score "+(i+1)+": ");
tests[i] = inputt.nextInt();
}
//Determine highest
int max = tests[0];
for (int i = 1; i < numTest; i++)
{
if (tests[i] > max)
{
max = tests[i];
}
}
//Determine Lowest
int least = tests[0];
for (int i = 1; i < numTest; i++)
{
if (tests[i] < least)
{
least = tests[i];
}
}
int sum = 0;
//Calculate total
for(int i =0; i< numTest;i++)
{
sum += tests[i];
}
//Subtract highest and least values
sum = sum - least - max;
//Calculate average
double average = sum / (numTest - 2);
//Print Average
System.out.println("Average = "+average);
//Print Highest
System.out.println("Highest = "+max);
//Print Lowest
System.out.print("Lowest = "+least);
}

3. the total amount the customer must pay

A succession of instructions written in a programming language for a computer to interpret is referred to as a computer program.
How is the program utilised?
The program gives the computer the expertise to carry out a specific task. A computer can function with the operating system without application software (apps), but it cannot carry out any particular task. For instance, you need to install Microsoft Word on your computer in order to generate a Word document.
Create a program that requests the price of each item, adds 5.5% sales tax, and shows the information below.
MARKETING TAX =.055
item1 is comparable to a float (input("Enter the price for item 1 in dollars"))
item2 = float('Enter the price for item 2 $', input)
item3 is equal to float(input("Enter the price for item 3 $"))
Float (item1 + item2 + item3) = subtotal
sales tax total = subtotal* SALES TAX
total is the aggregate of the subtotal and the sales tax.
Total = $ ('Total = $', format(total, ',.2f'), sep=", end=") ('nn')

What is computer program?Computer program is defined as a series of instructions written in a programming language that a computer may follow. Computers can obey a set of instructions created through coding. Programmers can create programs, including websites and apps, by coding.
Python says:
numA = [4, 1, 6, 10, 2, 3, 7, 9, 11, 12, 5, 8]
numB = [2, 12, 10, 11, 1, 3, 7, 9, 4, 8, 5, 6]
though True:
I = 0
input("Adding or Multiplying? (a/m)") userChoice
when userChoice equals "a"
even when I = len(numA):
What is input("What is + ".format(numA[i],numB[i]))? answer = int
if response == numA[i] + numB[i]:
print("Correct! ")
else:
print( "That is untrue. The appropriate response is "Formatted as (numA[i] + numB[i])
I += 1
if userChoice == "m," then
even when I = len(numA):
answer = int("What is *? ".format(numA[i], numB[i]))
if the response equals numA[i] + numB[i]:
print("Correct! ")
else
print( "that is untrue. The appropriate response is ".format(numB * numA[i]
I += 1
Thus, the program will give them a choice of practicing adding or multiplying is true.

Write a program called DeliveryCharges for the package delivery service in Exercise 4. The program should again use an array that holds the 10 zip codes of areas to which the company makes deliveries. Create a parallel array containing 10 delivery charges that differ for each zip code. Prompt a user to enter a zip code, and then display either a message indicating the price of delivery to that zip code or a message indicating that the company does not deliver to the requested zip code.
Answers
Answer:
zip_codes = ["11111", "22222", "33333", "44444", "55555", "66666", "77777", "88888", "99999", "00000"]
charges = [3.2, 4, 1.95, 5.7, 4.3, 2.5, 3.8, 5.1, 6.6, 7.3]
deliver = False
index = -1
zip_code = input("Enter the zip code: ")
for i in range(len(zip_codes)):
if zip_code == zip_codes[i]:
deliver = True
index = i
break
if deliver:
print("The charge of delivery to " + zip_codes[index] + " is $" + str(charges[index]))
else:
print("There is no delivery to " + zip_code)
Explanation:
*The code is in Python.
Initialize the zip_codes array with 10 zip codes
Initialize the charges array with 10 corresponding values
Initialize the deliver as False, this will be used to check if the zip code is in the zip_codes
Initialize the index, this will be used if the zip code is a valid one, we will store its index
Ask the user to enter the zip_code
Create a for loop that iterates the length of the zip_codes array. Inside the loop:
Check if the zip_code is equal to the any of the items in the zip_codes. If it is, set the deliver as True, set the index as i, and break
When the loop is done, check the deliver. If it is True, then print the charge of the delivery. Otherwise, print that there is no delivery to that zip code
How many rows of data are returned after executing the following statement?
SELECT DEPT_ID, SUM(SALARY) FROM EMP
GROUP BY DEPT_ID HAVING SUM(NVL(SALARY,100)) > 400;
Assume the EMP table has ten rows and each contains a SALARY value of 100, except for one, which has a null value in the SALARY field. The first and second five rows have DEPT_ID values of 10 and 20, respectively.
Answers
2 rows of data are returned after executing the following statement.
Two groups are created based on their common DEPT_ID values. The group with DEPT_ID values of 10 consists of five rows with
SALARY values of 100 in each of them. Therefore the SUM(NVL(SALARY,100)) function returns 500 for this group and it satisfies the
HAVING SUM(SALARY) > 400 clause. The group with DEPT_ID values of 20 has four rows with SALARY values of 100 and one row with
a null SALARY SUM(NVL(SALARY,100)) returns 500 and this group satisfies the HAVING clause. Therefore two rows are returned.
