More general output

Question

Hi,

The output of this is: (assume i enter 5): 5 x 3 = 15

But in the Console.WriteLine, i have to put '3' which is the value used by the method Prod.

My question is: by what could i replace '3' to be general? I tried with myObj.b but the value is still 5. I tried with myObj3.b but this gives an error (unreachable).

Thanks

using System;
class Hoofd
{
public int b = 2;
static void Main()
{
int g1 = 0;
Console.Write("Voer een geheel getal: ");
g1 = Convert.ToInt32(Console.ReadLine());

Hoofd myObj = new Hoofd();
myObj.b = 5;
Prod myObj2 = new Prod();
Console.WriteLine("{0} x {1} = {2}", g1, 3, myObj2.product(g1, myObj.b));
}
}
class Prod
{
Hoofd myObj3 = new Hoofd();//of in de method

public int product(int x, int y)
//public => bereikbaar vanuit Main
{
myObj3.b = 3;
return x * myObj3.b;
}
}

The value 3 is set while you call a method. On console.WriteLine(), the order of execution is from left to right. In my case, I am assigning this value while initialization, and it will be available at all times.

Thanks. I still don't understand why this code gives as output: 5 x 2 = 15 public static Hoofd myObj3 = new Hoofd() myObj3.b = 3; return x * myObj3.b; whereas this code gives 5 x 3 = 15 public static Hoofd myObj3 = new Hoofd() {b=3} return x * myObj3.b; According to me, in both cases is the value of myObj3 = 3, no?

Hi, Please find the modified code below, where you will be now getting the Prod value in general on your console.writeline() method. using System; class Hoofd { public int b = 2; static void Main() { int g1 = 0; Console.Write( "Voer een geheel getal: " ); g1 = Convert.ToInt32(Console.ReadLine()); Hoofd myObj = new Hoofd(); myObj.b = 5; Prod myObj2 = new Prod(); Console.WriteLine( "{0} x {1} = {2}" , g1, Prod.myObj3.b, myObj2.product(g1, myObj.b)); Console.ReadKey(); } } class Prod { public static Hoofd myObj3 = new Hoofd() { b=3 }; //of in de method public int product( int x, int y) //public => bereikbaar vanuit Main { // myObj3.b = 3; return x * myObj3.b; } }
