The BankAccount class implementation in Python 3.8 is found in the attached image

The deposit method  uses an if statement to check if the amount to be deposited is negative. If so, it does nothing, but returns False signifying that the transaction failed.

However, if the test finds out that the amount to deposit is positive or zero, the deposit method increments the balance, then returns True, signifying a successful transaction.

The withdraw method is similar, but this time, it tests if the amount to be withdrawn is greater than the available balance. If so, it ignores the transaction, and returns False.

If the withdrawal amount is less or equal to the available balance, the withdraw method decrements the available balance, then returns True, signifying a successful transaction.

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."

Proportional integral derivative (PID) control can measure the controlled variable and the system output and dynamically adjust the setpoint to achieve more precise control. It is an algorithm used in the industry.

An algorithm can be defined as a well-established list of rules/steps to follow to solve a given problem.

Proportional integral derivative (PID) control is the most widely used algorithm used in industry.

This type of control (PID) has different coefficients, i.e., proportional, integral and derivative coefficients, which vary in order to obtain an optimal response.

In this exercise we have to use the knowledge of the JAVA language to write the code, so we have to:

The code is in the attached photo.

So to make it easier the code can be found at:

using namespace std;

string fname;

int marks[3];

char grade;

// Function which generates the grade for student

double sum = 0;

for(int i=0;i<3;i++){

sum+= marks[i];

}

double average = sum/3;

if(average>=90 && average<100)

this->grade = 'A';

else if(average>=80)

this->grade = 'B';

else if(average>=70)

this->grade = 'C';

else if(average>=60)

this->grade= 'D';

else this->grade = 'F';

}

};

// This function reads the file , and creates a vector of Students data

vector read_file(string fileName){

// Opening the file

fstream fin;

fin.open(fileName);

// Temp variables

vector list;

st.marks[0] = stoi(row[2]);

st.marks[1] = stoi(row[3]);

st.marks[2] = stoi(row[4]);

st.calculate_grade();

list.push_back(st);

}

fin.close();

return list;

}

// This function takes filname to be output as input, and list of student
