Incomplete program

14y1.7kVisual Basic .NET

This incomplete program is given in the following website http://www.c-sharpcorner.com/UploadFile/rmcochran/csharp_memory01122006130034PM/csharp_memory.aspx. Whether it is possible to complete the program.

public class MyInt
{
        public int MyValue;

        and the following method is executing:

        public MyInt AddFive(int pValue)
        {
                MyInt result = new MyInt();
                result.MyValue = pValue + 5;
                return result;
        }
}

Here's one way in which you could complete it:

using System;

public class MyInt
{
public int MyValue;
}

class Program
{
static void Main()
{
Console.Write("Enter number to be increased by five : ");
int pValue = int.Parse(Console.ReadLine());
Program p = new Program();
MyInt mi = p.AddFive(pValue);
Console.WriteLine("{0} + 5 = {1}", pValue, mi.MyValue);
Console.ReadKey();
}

public MyInt AddFive(int pValue)
{
MyInt result = new MyInt();
result.MyValue = pValue + 5;
return result;
}

}

Alright Vulpes.... Thanks for the update.... ;)

Even if you use Convert.ToInt32(), it will still throw an exception if something that can't be parsed to an integer is passed such as 'abc' or 123.45.

When I write console applications myself, I always use int.TryParse rather than either int.Parse or Convert.ToInt32. I can then trap any invalid response and deal with it appropriately.

However, I haven't used it here as I didn't want to 'bog down' Maha with details of how it works, when the question is really being asked in relation to the difference between stack and heap allocation.

@ Vulpes - Hey while accepting the value for the pValue variable, I think we should always use "Convert.ToInt32() method" instead of int.Parse(). Because if null value is passed, then it might throw an exception.

What say???
