Question

I only need an answer for question #2

Write in c++

1.) Write the code to ask for an integer grade on a test. Validate the grade using a loop. Valid scores are 0-100.  

2.)Write the code to determine the letter grade for the test in the previous question. Use standard grade ranges. Assume all errors have already been dealt with in the code in the previous question.

Make sure to indent where needed

Answer 1

#include <iostream>

using namespace std;

int main() {
    int grade;
    cout << "Enter a grade(0-100): ";
    cin >> grade;
    while (grade < 0 || grade > 100) {
        cout << "Invalid range. Enter a grade(0-100): ";
        cin >> grade;
    }

    char letterGrade;
    if (grade >= 90)
        letterGrade = 'A';
    else if (grade >= 80)
        letterGrade = 'B';
    else if (grade >= 70)
        letterGrade = 'C';
    else if (grade >= 60)
        letterGrade = 'D';
    else
        letterGrade = 'F';
    cout << "Letter grade is " << letterGrade << endl;
    return 0;
