Parameter of oops

Parameter is used to make the dynamic methods ..

Parameter is 2 types ..

  • Input Parameter
  • Output Parameter

  • Input parameter :

    In input parameter is used to bringing the value In to the methods for execution are called as a input parameter .


    Output Parameter :

    In output parameter is used for carrying the value out of the method for execution are called as a output parameter ..


    We can send a value out of a methods in two ways :

  • Using return types
  • Using output parameters

  • A simple program using return statement :

    using System ;
    class Main {
    	public static void Main () {
    		int SomeInt=8;
    		int s =Sum(7,SomeInt);
    		Console.WriteLine(s);
    		Console.ReadLine();
    	}
    	public static int Sum (int x,int y ) {
    		return x+y;
    	}
    }
    

    Program for output Parameter :

    using System ;
    class outparam {
    	public void math (int a , int b , ref int c ,ref int d) {
    		c=a+b;
    		d=a*b;
    	}
    	public void math2(int a ,int b ,out in c ,out int d ) {
    		c=a-b;
    		d=a*b;
    	}
    	public void AddNums (int x ,int y=40 , int z=150) {
    		Console.WriteLine(x+y+z);
    	}
    	static void Main() {
    		Outparam op =new outparam();
    		op.AddNums(100);
    		op.AddNums(100,100);
    		op.AddNums(100 ,z ,100);
    		op.AddNums(100 ,100 ,100);
    		int x =0 ,y=0;
    		op.math1(100,40,ref x ,ref y);
    		Console.WriteLine(x + “ “ +y);
    		int m,n;
    		op.math2(100,30,out m, out n);
    		Console.WriteLine(m + “ “ +n);
    		Console.ReadLine();
    	}
    }
