Question

Write a program to run the following methods in C#.

2) Write a method that takes in a teacher’s last name and exam number via parameters. Ask the teacher (using her name) to tell you the highest score on that exam. Your question should look something like “Ms. Jones, what was the highest grade on test two?” Return the value of the highest grade to the calling method.

3) Write a function called MinOfThree that takes in three numbers and returns the smallest.

6) A parking lot charges a minimum fee of $5 to park for 2 hours, and then $1 for each additional hour. The maximum charge is $10.00 per day. Write a function named Fee that takes in the number of hours parked, and returns the amount of money owed.

7) Write a function that takes in a user’s hourly rate and hours worked. Calculate and return the user’s gross pay. The user gets time and one half for any time worked over 40 hour.

{
int GetHighestGrade(string name, string exam_number)
{
//Print the name and exam_num as concatenated string as below
Console.WriteLine("Ms. " + name + ", what was the highest grade on test " + exam_number + "?");
//Read the line and convert to int as below
int highest_grades = Convert.ToInt32(Console.ReadLine());
//return the value read
return highest_grades;
}

int MinOfThree(int a, int b, int c)
{
//if a is less than both b and c .. it is smallest
if ((a < b) && (a < c))

else //else we know a is not smallest, so now either b or c
{
if (b < c) //is b smallest ?
return b; //yes
else //no
return c; //hence c is smallest
}
}

int Fee(int num_of_hours)
{
int fee = 5; // it is base fee upto 2 hours
int max_fee = 10; //it is max for a day
  
if (num_of_hours <= 2) //so till 2 hours we charge base fee
return fee;

else //more than 2 hours
{

if (fee < max_fee) //but don't forget we can't charge more than max fee ie 10
return fee;
else
return max_fee;
}
}

double GrossPay(double hourly_rate, double hours_worked)
{
double gross_pay = hourly_rate * hours_worked; //thats how we calculate rate*time
if (hours_worked > 40)
{
//the user gets time and one half for any time worked over 40 hour.
//Not sure if I understand this condition right.
//I am assuming user gets bonus of 1/2 of his hourly rate for any hour worked over 40 hours
//Please comment if this condition is not this, and i will provide the correction
double overtime = hours_worked - 40;
gross_pay += (overtime * hourly_rate) / 2;

//Q.7 just passing the values here to method GrossPay.
//and reading the return value in a local variable
// hourly rate 12 and hours worked= 30
//You can change as per your requirment

//OUTPUT

Q.2 Ms. Jones, what was the highest grade on test two? 100 Highest grades: 100 Smallest of 33 , 6, 98 is 6 Q.6 Fee of parking for 5 hours is $8 The gross pay for 30 hours 12$/hr is $360
