Question

Write a C# program using Repl.it that asks the user for a numeric grade between 0 and 100, and displays a letter grade using the following conversion table:

Numeric grade   Letter grade

90 < grade <= 100 A

80 < grade <= 90 B

70 < grade <= 80 C

60< grade <= 70 D

grade <= 0.0 F

Don’t forget the comments in your code. The output should be similar to: Enter the test score: 87 The letter grade for a score of 87 is B. Submit the repl.it link to the text submission area of the assignment dropbox.

Answer 1

using System; // System is a namespace

class grade
{
// Main method which starts the program execution.
public static void Main()
{
  
Console.WriteLine("Enter the test score: ");
//take integer input
int number = Convert.ToInt32(Console.ReadLine());
  
//check for grade A
if (number > 90 && number<=100)
{
Console.WriteLine("The letter grade for a score of {0} is A.",number);
}
//check for grade B
else if(number > 80 && number<=90)
{
Console.WriteLine("The letter grade for a score of {0} is B.",number);
}
//check for grade C
else if(number > 70 && number<=80)
{
Console.WriteLine("The letter grade for a score of {0} is C.",number);
}
  
//check for grade D
else if(number > 60 && number<=70)
{
Console.WriteLine("The letter grade for a score of {0} is D.",number);
}
  
//check for grade Fail
else if(number < 60)
{
Console.WriteLine("The letter grade for a score of {0} is F.",number);
}
  
Console.ReadKey();
}
}
