Question

 

-You are going to write a program to help me determine the final grade and calculate some summary stats. The steps are described below:

1. First, create a dictionary of 10 students with student name as key and score as value.

•For simplicity, name students as student 1, student 2, etc. Scores are random integers from 0-100

2. Calculate the average score in the class

3. Determine the letter grade based on the following scheme

:•A if score >= average_score+10

•B if average+10 > score >= average_score

•C if average > score >= average_score-10

•D otherwise

4. Derive summary stats in terms of the # of As, Bs, Cs, and Ds.

−You program needs to output student scores, grades, average score, and summary stats.

Answer 1

**Code is given below**

using System;
using System.Collections.Generic;

public class Test
{
static double average_score=0;
static int A=0,B=0,C=0,D=0;

static char Grade(double score){
if(score>=average_score+10){A++;return 'A';}
else if(score>=average_score && score else if(score>=average_score-10 && score else{D++;return 'D';}
}

public static void Main(string[] args){
String key;
Random random=new Random();
Dictionary record=new Dictionary();
for(int i=1;i<=10;i++){
key="Student "+i;
record.Add(key,random.Next(101));
}

foreach(KeyValuePair value in record){
average_score+=value.Value;
}

average_score/=10;

foreach(KeyValuePair value in record){
Console.WriteLine("Student Name: {0}",value.Key);
Console.WriteLine("Score: {0}",value.Value);
Console.WriteLine("Grade: "+Grade(value.Value)+"\n");
}   
  
Console.WriteLine("Average score in the class: "+average_score);
Console.WriteLine("\nSummary Stats:");
Console.WriteLine("Number of As: "+A+"\nNumber of Bs: "+B+"\nNumber of Cs: "+C+"\nNumber of Ds: "+D);

}
}

**Code ended**

Output:
