Question

11. . Write a program using if-else statements that accepts a real number between 0 and 100 and, based on its value, reports its equivalent letter grade (A, B, C, D, or F). Add to your snapshots.

Write in c++

Answer 1

#include <iostream>
using namespace std;

int main() {
  
   double n;
   char grade;
  
   cout<<"Enter a number between 0.0 and 100.0 : ";
   cin>>n;
  
   if(n <= 100.0 && n>80.0)
   grade = 'A';
   else if(n <= 80.0 && n>70.0)
   grade = 'B';
   else if(n <= 70.0 && n>60.0)
   grade = 'C';
   else if(n <= 60.0 && n>40.0)
   grade = 'D';
   else if(n <= 40.0)
   grade = 'F';
  
  
  
   cout<<"\nGrade = "<<grade;
   return 0;
}

Output:

Enter a number between 0.0 and 100.0 : 67.8
Grade = C

Enter a number between 0.0 and 100.0 : 84.5
Grade = A

Enter a number between 0.0 and 100.0 : 33.6
Grade = F

Enter a number between 0.0 and 100.0 : 80.1
Grade = A

Do ask if any doubt.
