Answer:

Here's an example program in C++ that accepts an unknown number of grades and calculates the GPA and letter grade for each grade entered:

#include <iostream>

#include <vector>

#include <iomanip>

using namespace std;

int main() {

   int num_grades;

   vector<int> grades;

   double total_points = 0;

   double gpa;

   char letter_grade;

   // Get number of grades

   cout << "Enter number of grades: ";

   cin >> num_grades;

   // Get grades

   cout << "Enter grades (0-4): ";

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

       int grade;

       cin >> grade;

       if (grade >= 0 && grade <= 4) {

           grades.push_back(grade);

           total_points += grade;

       }

       else {

           grades.push_back(0);

       }

   }

   // Calculate GPA

   if (num_grades > 0) {

       gpa = total_points / num_grades;

   }

   else {

       gpa = 0;

   }

   // Output grades and GPA

   cout << fixed << setprecision(2);

   cout << "Grades and GPA:\n";

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

       int grade = grades[i];

       if (grade == 4) {

           letter_grade = 'A';

       }

       else if (grade == 3) {

           letter_grade = 'B';

       }

       else if (grade == 2) {

           letter_grade = 'C';

       }

       else if (grade == 1) {

           letter_grade = 'D';

       }

       else {

           letter_grade = 'F';

       }

       cout << "Grade " << i+1 << ": " << letter_grade << "\n";

   }

   cout << "GPA: " << gpa << "\n";

   return 0;

}

Explanation:

The program first prompts the user for the number of grades, then loops through that many times to get each grade from the user. If the grade entered is between 0 and 4, it is added to the grades vector and its value is added to total_points. Otherwise, a 0 is added to the grades vector instead.

After all grades have been entered, the program calculates the GPA by dividing total_points by the number of grades entered (making sure to check that num_grades is greater than 0 to avoid a divide-by-zero error).

Finally, the program loops through each grade in the grades vector, converts it to a letter grade, and outputs both the letter grade and the GPA. Note that fixed and setprecision(2) are used to format the GPA to two decimal places.

Here's a pseudocode version of the program:

Prompt the user to enter the number of grades to be entered

Read in the number of grades to be entered

Initialize a variable to hold the sum of the grades

Initialize a variable to hold the count of valid grades

Initialize an empty array to hold the entered grades

Loop through the number of grades entered:

a. Read in the next grade

b. If the grade is between 0 and 4, add it to the sum of the grades and increment the count of valid grades

c. If the grade is not between 0 and 4, set it to 0

d. Add the grade to the array of entered grades

Calculate the GPA by dividing the sum of the grades by the count of valid grades

Output the calculated GPA

Loop through the array of entered grades:

a. Calculate the letter grade for each grade based on the grading scale provided in the prompt

b. Output the letter grade for each grade

Note: It's important to validate the input grades to ensure they fall within the accepted range of 0-4. This is why step 6c is included, and why any invalid grades are set to 0. Additionally, some schools or institutions may use different grading scales, so it's important to verify that the provided grading scale matches the one being used before implementing this program in a real-world scenario.

Answer: Code bits.

Explanation:

HDLC (High-level Data Link Control) is a protocol used for transmitting data over a communication link. The HDLC frame consists of several fields, including the control field, which contains information about the flow and control of data. The control field in HDLC always includes three code bits, which identify the type of frame and the status of the communication. These code bits are always present in the control field, regardless of the type of frame or the data being transmitted. The other fields in the control field, such as N(S) and N(R), are used for sequence numbering and acknowledgment of frames, respectively, but they may not be present in all frames. Therefore, the correct answer is "Code bits."

Answer:

Assuming we have a register for holding the result, the following assembly code will add 1 and 2 together and store the result in the register, then print the result to the console:

mov eax, 1  ; move the value 1 into the eax register

add eax, 2  ; add the value 2 to the eax register

mov ebx, eax ; move the value in eax into the ebx register

; At this point, ebx contains the result of 1 + 2

To print the result, we can use system calls. The specific system calls required will depend on the operating system being used. Here is an example using the Linux system call interface:

mov eax, 4  ; system call number for "write" (printing to console)

mov ebx, 1  ; file descriptor for stdout

mov ecx, ebx ; pointer to the string to be printed

mov edx, 1  ; length of the string to be printed (in bytes)

int 0x80   ; call the kernel to perform the write operation

; convert the result to a string and print it

add ebx, 48  ; convert result to ASCII code for printing

mov ecx, ebx ; move result to ecx for printing

mov edx, 1  ; length of the string to be printed (in bytes)

mov eax, 4  ; system call number for "write" (printing to console)

int 0x80   ; call the kernel to perform the write operation

Explanation:

This will print the result of 1 + 2 to the console as the character "3".

# Prompt the instructor to enter three exam scores

average_score = (score1 + score2 + score3) / 3

# Calculate the average grade based on the average exam score

if average_score >= 90:

   average_grade = "A"

elif average_score >= 80:

   average_grade = "B"

elif average_score >= 70:

   average_grade = "C"

elif average_score >= 60:

   average_grade = "D"

else:

   average_grade = "F"

# Display the average grade in fixed-point notation with two decimal points of precision

print("The average grade is: {:.2f} ({})".format(average_score, average_grade))

Explanation:

Sample Run:

Enter the first exam score: 85

Enter the second exam score: 78

Enter the third exam score: 92

The average grade is: 85.00 (B)

The given Python program determines the corresponding letter grade based on the average score, and then displays the average score and grade with the desired formatting.

What is Python?
Python is a high-level, interpreted programming language that was first released in 1991. It is designed to be easy to read and write, with a simple and intuitive syntax that emphasizes code readability. Python is widely used in various fields such as web development, data science, machine learning, and scientific computing, among others.

Python Code:

# Prompt the user to enter three exam scores

exam1 = float(input("Enter score for Exam 1: "))

exam2 = float(input("Enter score for Exam 2: "))

exam3 = float(input("Enter score for Exam 3: "))

# Calculate the average exam score

average = (exam1 + exam2 + exam3) / 3

# Determine the letter grade based on the average score

if average >= 90:

   grade = 'A'

elif average >= 80:

   grade = 'B'

elif average >= 70:

   grade = 'C'

elif average >= 60:

   grade = 'D'

else:

   grade = 'F'

# Display the average score and grade

print("Average score: {:.2f}".format(average))

print("Grade: {}".format(grade))

In this program, we use the float() function to convert the input values from strings to floating-point numbers. We then calculate the average score by adding up the three exam scores and dividing by 3. Finally, we use an if statement to determine the letter grade based on the average score, and we use the .format() method to display the average score and grade with the desired formatting. The :.2f notation in the format string specifies that the average score should be displayed with two decimal places.
