Question

Write a program that asks the user to input a grade that he or she received on an exam. The grade is an integer from 0-100 inclusive. The program should convert the numeric grade into the equivalent letter grade. Do the conversion by using a function Letter_Grade() that converts a numeric grade in the range 0-100; B if the grade is 80-89; C if the grade is 70-79; D if the grade is 65-69; and F if the grade is 64 or lower. After converting the grade, the program should display the numeric grade and the equivalent letter grade.

In order to count for grade, you must use at least one function to implement the program as described in the assignment requirements.

Again the assignment requires the use of a function within the code. The integer output must also be reflected as a percentage with decimals not just a number.

Please use C++

Explanation / Answer

#include <iostream>
using namespace std;

char calculate_grade( int percent ) {
    if ( percent >= 90 ) return 'A';
    if ( percent >= 80 ) return 'B';
    if ( percent >= 70 ) return 'C';
    if ( percent >= 65 ) return 'D';
    return 'F';
}

int main( int argc, char **argv ) {
    int percent;

    cout << "Enter your percentage grade (0-100) ";
    cin >> percent;

    if ( percent > 100 || percent < 0 ) {
        cerr << "Invalid grade." << endl;
    }

    cout << "Your grade is " ;
    cout.precision(2);
    cout << fixed << (float)percent;
    cout << "%. Your letter grade is " <<
            calculate_grade( percent ) << endl;
}
