If (iqscore < 0) || (iqscore > 200) , error 2: throw new inputexception(string.format("iqscore is out of range: score should range from 0 to 200")); }

Question

1.00/5 (2 votes)

See more:

Write an application that asks a user to enter an IQ score. If the score is a number less than 0 or greater than 200, issue an error message; otherwise, issue an “above average”, “average”, or “below average” message for scores over, at, or under 100, respectively.

What I have tried:

C#

using System;

namespace Question_5
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("What is your IQ score");
            int IQScore = Convert.ToInt32(Console.ReadLine());

            if (IQScore < 0) || (IQScore > 200)
            {
                throw new InputException(string.Format("IQScore is out of range: score should range from 0 to 200"));
            }
         else if (IQScore < 100)
            {
                Console.WriteLine("IQScore is average");
            }
            else
            {
                Console.WriteLine("IQCore is above average");
            }
            Console.ReadKey();
        }
    }
}

Solution 1

In your program, you are missing the parenthesis with if clause. Use the correct Exception class, Correct your code accordingly:

if ((IQScore < 0) || (IQScore > 200))
{
      throw new Exception(string.Format("IQScore is out of range: score should range from 0 to 200"));
}

Sir i got many errors in this program of C# (methods) how can i fix this?

Question: Add another method called ShowMenu() to your project. This method will call the
method in question 7 continuously until the user presses 0. (You will have to invoke
the method in a loop body, read in the user input as well as check the input). You
will need to hook up all the methods that you wrote previously i.e. questions 1 to 6.
Replace all the code from your Main() method with a single call to the
ShowMenu() method.

using System;

namespace Q8
{
internal class Program
{
static void Main(string[] args)
{
static void ShowMenu()
{
int choice;
do
{
DisplayMenu();
choice = Convert.ToInt32(Console.ReadLine());

switch (choice)
{
case 1:
DisplayPersonalInfo();
break;
case 2:
CalculateTuition();
break;
case 3:
CalculateAreaOfCircle();
break;
case 4:
CalculateAreaOfTriangle();
break;
case 5:
for (int i = 1; i <= 3; i++)
{
CalculateSaleCommission();
}
break;
case 6:
DisplaySineTable();
break;
}
}
while (choice != 0);
}
}
}

}
