Question

C++

Write a program which accepts a numeric test score from the user. It will output the letter grade to the user corresponding to the score. Assume no “minus grades” (an A ranges from 90-100, B ranges from 80-89, C ranges from 70-79, D ranges from 60-69 and F is everything else.) Ensure that the score remains in the range of 0 to 100. As an example of the output:

   Enter your numeric grade and I will tell you your output: 74
   Your grade is a C.

Answer 1

#include <iostream>

using namespace std;

char getLetterGrade(double average){
   char letter;
   if(average < 60)
        letter = 'F';
    else if(average < 70)
        letter = 'D';
    else if(average < 80)
        letter = 'C';
    else if(average < 90)
        letter = 'B';
    else
        letter = 'A';
    return letter;
}

int main(){
   double averageScore;
   cout<<"Enter your numeric grade and I will tell you your output: ";
    cin>>averageScore;
    cout<<"Your grade is a "<<getLetterGrade(averageScore)<<"."<<endl;
    return 0;
}
