Description

Write a program that computes the letter grades of students in a class from knowing their scores in a test. A student test score varies from 0 to 100. For a student, the program first asks the students name and the students test score. Then, it displays the student name, the test score and the letter grade. It repeats this process for each student. The user indicates the end of student data by entering two consecutive forward slashes ( // ) when asked for the student name. At the end, the program displays a summary report including the following:

The total number of students.

The total number of students receiving grade A.

The total number of students receiving grade B.

The total number of students receiving grade C.

The total number of students receiving grade D.

The total number of students receiving grade F.

The program calculates a student's the letter grade from the student's test score as follows:

A is 90 to 100 points

B is 80 to 89 points

C is 70 to 79 points

D is 60 to 69 points

F is 0 to 59 points.

Requirements

Do this exercise using a While statement and an If/Else If statement.

Sample Code

char grade;

string name;

double score;

int aCount=0, bCount=0, cCount=0, dCount=0, fCount=0;

//Initias setup

cout << "Enter student name" << endl;

cin >> name;

//Test

while (name != "//")

{

cout << "Enter student score" << endl;

cin >> score;

if (score>=90.0){

grade = "A";

aCount++;

}

else if (score>=80.0){

grade = "B";

bCount++;

}

//more code here

cout << name << " " << score << " " << grade << endl;

//Update setup

out << "Enter student name" << endl;

cin >> name;

}

int totalCount=aCount+bCount+cCount+dCount+fCount;

//display summary report

cout<<"Total Students count " << totalCount << endl;
