Exception handling in C#

If error is frequent you have to use TRADITIONAL ERROR-HANDLING METHODS (that is IF test). The creators of C# define more than 30% is frequent.

If error is infrequent (that is exception) you have to use try catch. Less than 30% is infrequent.


Traditional Error Handling Methods example:

using System;
public class MathErrorPreventedWithIf
{
public static void Main()
{
int num, denom, result;
DataEntry(out num, out denom);

if (denom != 0)
result = num / denom;
else
{
Console.WriteLine("Attempt to divide by 0. Denominator replaced with 1");
result = num / 1;

}
Console.WriteLine("Result is {0}", result);
}
public static void DataEntry(out int num, out int denom)
{
Console.Write("Enter a number ");
num = Convert.ToInt32(Console.ReadLine());

Console.Write("Enter a number to divide into the first ");
denom = Convert.ToInt32(Console.ReadLine());
}
}
