Parameter of oops

Parameter is used to make the dynamic methods ..

Parameter is 2 types ..

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 :

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();
	}
}
