Program

open System  
let getGrade marks = 
    if(marks<0 && marks>100) then  
        Console.WriteLine("Wrong Marks entered")  
    elif(marks>=0 && marks<50) then  
        Console.WriteLine("Fail")  
    elif(marks>=50 && marks<60)then  
        Console.WriteLine("D Grade") 
    elif(marks>=60 && marks<70) then  
        Console.WriteLine("C Grade")
    elif(marks>=70 && marks<80)then  
        Console.WriteLine("B Grade")  
    elif(marks>=80 && marks<90)then  
        Console.WriteLine("A Grade") 
    elif(marks>=90 && marks<=100)then  
        Console.WriteLine("A+ Grade")  
Console.Write("Enter the marks obtained to check the grade: ")  
let marks = Int32.Parse(Console.ReadLine())  
let grade = getGrade marks
