This C# console application is designed to:
|
||||||
|
- Use arrays to store student names and assignment scores.
|
||||||
|
- Use a `foreach` statement to iterate through the student names as an outer program loop.
|
||||||
|
- Use an `if` statement within the outer loop to identify the current student name and access that student's assignment scores.
|
||||||
|
- Use a `foreach` statement within the outer loop to iterate though the assignment scores array and sum the values.
|
||||||
|
- Use an algorithm within the outer loop to calculate the average exam score for each student.
|
||||||
|
- Use an `if-elseif-else` construct within the outer loop to evaluate the average exam score and assign a letter grade automatically.
|
||||||
|
- Integrate extra credit scores when calculating the student's final score and letter grade as follows:
|
||||||
|
- detects extra credit assignments based on the number of elements in the student's scores array.
|
||||||
|
- divides the values of extra credit assignments by 10 before adding extra credit scores to the sum of exam scores.
|
||||||
|
- use the following report format to report student grades:

/*

This C# console application is designed to:
|
||||||
|
- Use arrays to store student names and assignment scores.
|
||||||
|
- Use a `foreach` statement to iterate through the student names as an outer program loop.
|
||||||
|
- Use an `if` statement within the outer loop to identify the current student name and access that student's assignment scores.
|
||||||
|
- Use a `foreach` statement within the outer loop to iterate though the assignment scores array and sum the values.
|
||||||
|
- Use an algorithm within the outer loop to calculate the average exam score for each student.
|
||||||
|
- Use an `if-elseif-else` construct within the outer loop to evaluate the average exam score and assign a letter grade automatically.
|
||||||
|
- Integrate extra credit scores when calculating the student's final score and letter grade as follows:
|
||||||
|
- detects extra credit assignments based on the number of elements in the student's scores array.
|
||||||
|
- divides the values of extra credit assignments by 10 before adding extra credit scores to the sum of exam scores.
|
||||||
|
- use the following report format to report student grades:
|
||||||
|
|
||||||
|

This application manages transactions at a store check-out line. The
|
||||||
|
check-out line has a cash register, and the register has a cash till
|
||||||
|
that is prepared with a number of bills each morning. The till includes
|
||||||
|
bills of four denominations: $1, $5, $10, and $20. The till is used
|
||||||
|
to provide the customer with change during the transaction. The item
|
||||||
|
cost is a randomly generated number between 2 and 49. The customer
|
||||||
|
offers payment based on an algorithm that determines a number of bills
|
||||||
|
in each denomination.
|
||||||
|
|
||||||
|
Each day, the cash till is loaded at the start of the day. As transactions
|
||||||
|
occur, the cash till is managed in a method named MakeChange (customer
|
||||||
|
payments go in and the change returned to the customer comes out). A
|
||||||
|
separate "safety check" calculation that's used to verify the amount of
|
||||||
|
money in the till is performed in the "main program". This safety check
|
||||||
|
is used to ensure that logic in the MakeChange method is working as
|
||||||
|
expected.

/*
|
||||||
|
This application manages transactions at a store check-out line. The
|
||||||
|
check-out line has a cash register, and the register has a cash till
|
||||||
|
that is prepared with a number of bills each morning. The till includes
|
||||||
|
bills of four denominations: $1, $5, $10, and $20. The till is used
|
||||||
|
to provide the customer with change during the transaction. The item
|
||||||
|
cost is a randomly generated number between 2 and 49. The customer
|
||||||
|
offers payment based on an algorithm that determines a number of bills
|
||||||
|
in each denomination.
|
||||||
|
|
||||||
|
Each day, the cash till is loaded at the start of the day. As transactions
|
||||||
|
occur, the cash till is managed in a method named MakeChange (customer
|
||||||
|
payments go in and the change returned to the customer comes out). A
|
||||||
|
separate "safety check" calculation that's used to verify the amount of
|
||||||
|
money in the till is performed in the "main program". This safety check
|
||||||
|
is used to ensure that logic in the MakeChange method is working as
|
||||||
|
expected.

This application manages transactions at a store check-out line. The
|
||||||
|
check-out line has a cash register, and the register has a cash till
|
||||||
|
that is prepared with a number of bills each morning. The till includes
|
||||||
|
bills of four denominations: $1, $5, $10, and $20. The till is used
|
||||||
|
to provide the customer with change during the transaction. The item
|
||||||
|
cost is a randomly generated number between 2 and 49. The customer
|
||||||
|
offers payment based on an algorithm that determines a number of bills
|
||||||
|
in each denomination.
|
||||||
|
|
||||||
|
Each day, the cash till is loaded at the start of the day. As transactions
|
||||||
|
occur, the cash till is managed in a method named MakeChange (customer
|
||||||
|
payments go in and the change returned to the customer comes out). A
|
||||||
|
separate "safety check" calculation that's used to verify the amount of
|
||||||
|
money in the till is performed in the "main program". This safety check
|
||||||
|
is used to ensure that logic in the MakeChange method is working as
|
||||||
|
expected.
