Question

Implement a program (in both C# and Python) which includes a user-defined exception giving a message “This score is too low. You failed the exam.” if a score is less than 50. Otherwise, it should give a message “You passed the exam. Congratulations.”.

Answer 1

C# CODE

Code to copy:

// C# CODE:

using System;

// user-defined exception class

class LowResult : Exception

{

// base is used to access members of the base class

// All exceptions inherit from System.Exception class

public LowResult() : base("This score is too low. You failed the exam.")

{}

}

// main class

class MainClass

{

public static void Main (string[] args)

{

try

{

// prompt user to enter the score

Console.WriteLine("Enter the Score: ");

// read the user input as int

// Convert.ToInt32() converts string to int

int score = Convert.ToInt32(Console.ReadLine());

// Check if score is less than 50

if(score < 50)

{

// throw the exception that arises

throw new LowResult();

}

else

{

// display the student passed the exam

Console.WriteLine("You passed the exam. Congratulations.");

}

}

// catch the error thrown within the try-block

catch(LowResult e)

{

// display the error message

Console.WriteLine(e.Message);

}

}

}

PYTHON CODE

Code to copy:

# PYTHON CODE:

# User-defined class for low score

class LowResult(Exception):

pass

# main program

try:

# prompt to enter score

score = int(input("Enter the Score: "))

# check if the score is less than 50

if score < 50:

# raise the defined error

raise LowResult()

else:

# display the student passed

print("You passed the exam. Congratulations.")

except:

# display the error message

print("This score is too low. You failed the exam.")
