The Programming Language is C++

Objective:

The purpose of this project is to expose you to:

One-dimensional parallel arrays, input/output, Manipulating summation, maintenance of array elements. In addition, defining an array type and passing arrays and array elements to functions.

Problem Specification:

Using the structured chart below, write a program to keep records and print statistical analysis for a class of students. There are three quizzes for each student during the term. Each student is identified by a four-digit student ID number. The number of students in the class is unknown, therefore we need to detect end of file to stop. The file pr2data.txt is included and contains the data.

The program calculates the statistics for each student and for each quiz as shown in the sample output. The output goes to a file and is in the same order as the input and should be similar to the following: any other improvements to the output are welcomed.

Requirements:

• Main () is used as a driver function; the only statements in main are function calls.
• Your program needs to follow my hierarchical chart.
• Define a new type for each array of a type.
• Declare an array for each of the data items.
• Setdata() reads the data from the file into arrays.
• Getdata prints the results into a file.
• Findstavg calculates each student’s average and stores it into an array.
• Findqzavg finds the average of a quiz and returns the average as its value
• Findhigh finds the largest quiz in an array and returns it as its value.
• Findlow finds the smallest quiz in an array and returns it as its value.

Design an Essay class that is derived from the GradedActivity class:

class GradedActivity{
private:
double score;
public:
GradedActivity()
{score = 0.0;}
GradedActivity(double s)
{score = s;}
void setScore(double s)
{score = s;}
double getScore() const
{return score;}

char getLetterGrade() const;
};

char GradedActivity::getLetterGrade() const{
char letterGrade;

if (score > 89) {
letterGrade = 'A';
} else if (score > 79) {
letterGrade = 'B';
} else if (score > 69) {
letterGrade = 'C';
} else if (score > 59) {
letterGrade = 'D';
} else {
letterGrade = 'F';
}

return letterGrade;
}

The Essay class should determine the grade a student receives on an essay. The student's essay score can be up to 100, and is made up of four parts:

• 
  
• Grammar: up to 30 points
• 
  
• Spelling: up to 20 points
• 
  
• Correct length: up to 20 points
• 
  
• Content: up to 30 points
• 
  
• 
  

The Essay class should have a double member variable for each of these sections, as well as a mutator that sets the values of these variables. It should add all of these values to get the student's total score on an Essay.

Demonstrate your class in a program that prompts the user to input points received for grammar, spelling, length, and content, and then prints the numeric and letter grade received by the student.

Write a Python program that prompts the user to enter a list of words and stores in a list only those words whose first letter occurs again within the word (for example, 'Baboon'). The program should display the resulting list..................please explain step by step

Create a Software Application for XYZ Bank that allows its members to access their bank account information through an “ATM like” interface. The Menu Options should include: checking the account balance, debiting the account and crediting the account, along with an option to exit the program.

Create an Account Class to represent the customers’ bank accounts. Include a data member of type float to represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member.

1. The constructor should validate the initial balance to ensure that it’s greater than or equal to $1000.00. If not, set the balance to 0 and display an error message to the user indicating that the initial balance was invalid.
2. Provide three member functions.

1. Member function Credit() should add an amount to the current balance.

1. 2. Member function Debit() should withdraw money from the Account and ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged and the function should print a message indicating "Debit amount exceeded account balance."
2. 3. Member function GetBalance() should return the current balance.

Can someone please help me in Creating a console application in C++ that meet the requirements outlined above. With comments Lines

In main():

1. Create the following list using addHead(). The list must be in the order shown below.

2. Print the complete list using toString() method.
3. Create another list using AddTail(). The list must be in the order shown below.
4. Print the complete list using toString() method.
5. Delete head note from both list.
6. Print the both list using toString() method.

7. Add following methods in the previous lab program

8. Demonstrate all the above methods by calling in them in main.

How would i write a MIPS program that converts 2 decimals to binary

What would be the result of each of the following programs?

Write a C function gcd that returns the greatest common divisor of two integers. The greatest common divisor (GCD) of two integers is the largest integer that evenly divides each of the two numbers.

Q6.13) Unary minuses can be added in several ways to the arithmetic expression grammar of Figure 6.17 or Figure 6.18. Revise the BNF and EBNF for each of the cases that follow so that it satisfies the stated rule:

expr → expr + term | term

term → term * factor | factor

factor → ( expr ) | number

number → number digit | digit

digit → 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9

[Figure 6.17. Revised grammar for simple integer arithmetic expressions]

expr → term { + term }

term → factor { * factor }

factor → ( expr ) | number

number → digit { digit }

digit → 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9

[Figure 6.18 EBNF rules for simple integer arithmetic expressions]

(a) At most, one unary minus is allowed in each expression, and it must come at the beginning of an expression, so -2 + 3 is legal (and equals 1) and -2 + (-3) is legal, but -2 + -3 is not.

(b) At most, one unary minus is allowed before a number or left parenthesis, so -2 + -3 and -2 * -3 are legal, but --2 and -2 + --3 are not.

(c) Arbitrarily many unary minuses are allowed before numbers and left parentheses, so everything above is legal.

This is a request for Java High Scores Program with 2 files.

Rewrite the high scores assignment(code below) so that the names and scores are stored in an array of HighScore objects instead of parallel ArrayLists.

The new Program should have the same output as the original. Here is a sample run of the program:

Enter the name for score #1: Suzy

Enter the score for score #1: 600

Enter the name for score #2: Kim

Enter the score for score #2: 9900

Enter the name for score #3: Bob

Enter the score for score #3: 1012

Enter the name for score #4: Armando

Enter the score for score #4: 8000

Enter the name for score #5: Tim

Enter the score for score #5: 514

Top Scorers:

Kim: 9900

Armando: 8000

Bob: 1012

Suzy: 600

Tim: 514

Step 1: The HighScores class

Begin by creating the HighScore class. It should have the following design

Class HighScore

Step 2: The HighScoresProgram

Create a separate file named HighScoresProgram.java. This file should contain a class that has only four following static methods.

public static void main(String args[])

public static void initialize(HighScores[] scores)

public static void sort(HighScores[] scores)

public static void display(HighScores[] scores)

The main method should allocate an array of five HighScore references, and then invoke the other three methods.
