# Guided Project
|
|||
|
|
|
|||
|
|
## Calculate and print student grades
|
|||
|
|
|
|||
|
|
### Introduction
|
|||
|
|
|
|||
|
|
Developers perform some tasks nearly every day. Tasks including declaring
|
|||
|
|
string and numeric variables, assigning and extracting values, and performing
|
|||
|
|
calculations are routine, but essential. Equally important is the task of
|
|||
|
|
communicating results to the application user. Mastering the ability to apply
|
|||
|
|
these skills to solve a given problem is something that every developer must
|
|||
|
|
learn to do.
|
|||
|
|
|
|||
|
|
Suppose you are a teacher's assistant at a school. You're tasked with
|
|||
|
|
developing an application that automates student grading. The application uses
|
|||
|
|
all of the scored assignments for each student to calculate their current
|
|||
|
|
overall grade/score for the class. The teacher has also provided a required
|
|||
|
|
format for reporting the student grades.
|
|||
|
|
|
|||
|
|
This module will guide you through the steps required to develop your Student
|
|||
|
|
Grading application. Your code will declare and assign values to variables
|
|||
|
|
based on student names, perform various numeric calculations, and display the
|
|||
|
|
results. Calculations include determining the sum of assignment scores and
|
|||
|
|
calculating the current grade for each student. To display the results in the
|
|||
|
|
required format, you'll use Console.WriteLine(), as well character escape
|
|||
|
|
sequences that will help format your results.
|
|||
|
|
|
|||
|
|
By the end of this module, you'll be able to write code that uses various
|
|||
|
|
variable types, performs numeric calculations, and displays formatted data for
|
|||
|
|
the user.
|
|||
|
|
|
|||
|
|
> Note
|
|||
|
|
> This is a guided project module where you'll complete an end-to-end project
|
|||
|
|
by following step-by-step instructions.
|
|||
|
|
|

|
|
|
|||
|
|
- Work with variables to store and retrieve data
|
|||
|
|
- Perform basic math operations
|
|||

|
|||
|
|
|
|||
|
|

## Prepare for guided project
|
|||
|
|
|
|||
|
|
You'll be using the .NET Editor as your code development environment. You'll
|
|||
|
|
be writing code that uses string and numeric variables, performs calculations,
|
|||
|
|
and displays results to a console.
|
|||
|
|
|
|||
|
|
### Project overview
|
|||
|
|
|
|||
|
|
You're developing a Student Grading application that automates the calculation
|
|||
|
|
of current grades for each student in a class. The parameters for your
|
|||
|
|
application are:
|
|||
|
|
|
|||
|
|
- You're given a short list of four students and their five assignment grades.
|
|||
|
|
- Each assignment grade is expressed as an integer value, 0-100, where 100
|
|||
|
|
represents 100% correct.
|
|||
|
|
- Final scores are calculated as an average of the five assignment scores.
|
|||
|
|
- Your application needs to perform basic math operations to calculate the
|
|||
|
|
final grades for each student.
|
|||
|
|
- Your application needs to output/display each student’s name and final score.
|
|||
|
|
|
|||
|
|
Currently, the teachers grade book shows the graded assignments for each student as follows:
|
|||
|
|
|
|||
|
|
|
|||
|
|
| Name | G1 | G2 | G3 | G4 | G5 |
|
|||
|
|
| :- | :-: | :-: | :-: | :-: | :-: |
|
|||
|
|
| Sophia | 93 | 87 | 98 | 95 | 100 |
|
|||
|
|
| Nicolas | 80 | 83 | 82 | 88 | 85 |
|
|||
|
|
| Zahirah | 84 | 96 | 73 | 85 | 79 |
|
|||
|
|
| Jeong | 90 | 92 | 98 | 100 | 97 |
|
|||
|
|
|
|||
|
|
The teacher requires that the calculated grades for each student are displayed
|
|||
|
|
as follows:
|
|||
|
|
|
|||
|
|
```txt
|
|||
|
|
Student Grade
|
|||
|
|
Sophia 94.6 A
|
|||
|
|
Nicolas 83.6 B
|
|||
|
|
Zahirah 83.4 B
|
|||
|
|
Jeong 95.4 A
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Setup
|
|||
|
|
|
|||
|
|
Use the following steps to prepare for the Guided project exercises:
|
|||
|
|
|
|||
|
|
Open the .NET Editor coding environment.
|
|||
|
|
|
|||
|
|
Copy and paste the following code into the .NET Editor. These values represent
|
|||
|
|
the graded assignments for each student.
|
|||
|
|
|
|||
|
|
```cs
|
|||
|
|
// initialize variables - graded assignments
|
|||
|
|
int currentAssignments = 5;
|
|||
|
|
|
|||
|
|
int sophia1 = 93;
|
|||
|
|
int sophia2 = 87;
|
|||
|
|
int sophia3 = 98;
|
|||
|
|
int sophia4 = 95;
|
|||
|
|
int sophia5 = 100;
|
|||
|
|
|
|||
|
|
int nicolas1 = 80;
|
|||
|
|
int nicolas2 = 83;
|
|||
|
|
int nicolas3 = 82;
|
|||
|
|
int nicolas4 = 88;
|
|||
|
|
int nicolas5 = 85;
|
|||
|
|
|
|||
|
|
int zahirah1 = 84;
|
|||
|
|
int zahirah2 = 96;
|
|||
|
|
int zahirah3 = 73;
|
|||
|
|
int zahirah4 = 85;
|
|||
|
|
int zahirah5 = 79;
|
|||
|
|
|
|||
|
|
int jeong1 = 90;
|
|||
|
|
int jeong2 = 92;
|
|||
|
|
int jeong3 = 98;
|
|||
|
|
int jeong4 = 100;
|
|||
|
|
int jeong5 = 97;
|
|||
|
|
```
|
|||
|
