Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90= B: 80=< X < 90
C: 70=< X < 80
D: 60=< X < 70
E: X < 60
Compute the average of each exam.
• Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt.
• Output one student per row and separate the values with a tab character.
• Output the average of each exam, with two digits after the decimal point at the end of report.txt. Hint: Use the setprecision manipulator to format the output.
Ex: If the input of the program is:
StudentInfo.tsv
and the contents of Studentinfo tsv are:
Barrett Edan 70 45 59
Bradshaw Reagan 96 97 88
Charlton Caius 73 94 80
Mayo Tyrese 88 61 36
Stern Brenda 90 86 45
the file report.txt should contain:
Barrett Edan 70 45 59 F
Bradshaw Reagan 96 97 88 A
Charlton Caius 73 94 80 B
Mayo Tyrese 88 61 36 D
Stern Brenda 90 86 45 C
Averages: midtermi 83.40, midterm2 76.60, final 61.60

Summary
In this lab, you use a counter-controlled while loop in a Python program. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and output statements.
Instructions
Make sure the file Multiply.py is selected and opened.
Write a counter-controlled while loop that uses the loop control variable (numberCounter) to take on the values 0 through 10.
In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop.
Execute the program by clicking the "Run Code" button at the bottom of the screen.

What is the result of s1.compareTo(s2)?

A. true
B. false
C. 0
D. 1

Consider the following declarations:
String s1 = "apple";
String s2 = "APPLE";
Which of the following expressions is true?

A. s1.equals(s2) && s1.equalsIgnoreCase(s2)
B. !s1.equals(s2) && s1.equalsIgnoreCase(s2)
C. s1.equals(s2) && !s1.equalsIgnoreCase(s2)
D. !s1.equals(s2) && !s1.equalsIgnoreCase(s2)

Answers

Answer:

B, C, B

Explanation:

According to my understanding of these questions, these are in Java.

For the first one, there is a built in function called .length() for a string, so it's answer B.

For the second one, this should come out as C, 0 since compareTo compares the ascii values of the characters.

The third one's answer should be B. s1.equals(s2) for characters that are caps and not caps comes out with false, so ! would negate it. s1.equalsIgnoreCase(s2) would come out as true, ignoring the cases of APPLE.

An ATM allows a customer to withdraw maximum amount of 500

Answers

Answer:

true

Explanation:

Algorithm:

Print "Enter the initial amount: $"
Get totalAmount

Repeat the following steps until totalAmount <= 0 or the user wants to exit
Get withdrawAmount

if withdrawAmount > 500
Print "You cannot withdraw amount of $500 per day."
otherwise
serviceCharge = 0

if withdrawAmount > 300
Find the serviceCharge as below
serviceCharge = (withdrawAmount - 300) * 0.04

Find the deductions as below
deductions = withdrawAmount + serviceCharge

if deductions > totalAmount
Print "Insufficient funds!"
Print "Allow with a service charge of $25? (Y/N): "
Get choice

if choice == 'y' or choice == 'Y'
Find the totalAmount as below
totalAmount -= (deductions + 25)
Print "Service charges: $" serviceCharge
Print "Additional charge: $25"
Print "Current balance: $" totalAmount
otherwise
Find the totalAmount as below
totalAmount -= deductions
Print "Service charges: $" serviceCharge
Print "Current balance: $" totalAmount

if totalAmount > 0
Print "Continue to withdraw? (Y/ N): "
Get choice;

if choice != 'y' and choice != 'Y'
Print "Current balance: $" totalAmount
Set repeat = false;

if totalAmount <= 0
Print "You should deposit an amount of money."

how to count binary ? Help Better understand this question

Answers

Explanation:

For each row in the picture, you have to switch on some of the bits to create the number on the left.

Each bit has a value, a "weight" so to speak. By switching on the bit, you add that weight to the sum.

These "weights" are shown at the top row.

So to create 4, it's easy, you just switch on the '4' bit.

Same for 128, only one bit has to be switched on.

40 is a bit more involved, now you have to switch on 32 and 8, since 32+8 is 40.

For every number, there is exactly one combination of switched on bits to create that number. In the case of 40, the binary representation is:

00101000.

Answers

Mobile CPUs are found in laptops and are often slower than their desktop counterparts because they have to be more power-efficient and generate less heat. High power consumption and high heat generation can be a problem for a battery-powered laptop with a relatively small chassis
