Function in c#

 

 

Function:

 

Ex.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

 

namespace ConsoleApp2

{

    class Program

    { void display()

        {

            Console.WriteLine("welcome");

        }

        static void Main(string[] args)

        {

            //create object

            //classname objname = new classname();

            Program p1 = new Program();

            p1.display();

            Console.ReadKey();

        }

    }

}

 

 

 

# function parameters:- all the parameters are declared inside the function brackets().

Ex. Display(a)

Ex.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

 

namespace ConsoleApp2

{

    class Program

    { void display(int a )// receiver parameters

        {

            Console.WriteLine(a);

            Console.WriteLine("welcome");

        }

        static void Main(string[] args)

        {

            //create object

            //classname objname = new classname();

            Program p1 = new Program();

            p1.display(20);// sender parameters

            Console.ReadKey();

        }

    }

}

# input concept:-

All types of input fundamentals are declared  in MAIN BODY.

 

Ex of program with the help of user input

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

 

namespace input

{

    class Program

    {                       // creating input function

        void input(int roll,string name)

        {                  // printing input function parameters

            Console.WriteLine(roll);

            Console.WriteLine(name);

        }

        static void Main(string[] args)

        {// creating variable for input

            int roll1;

            string name1;

            Console.WriteLine("Enter your roll no.");

            roll1 = int.Parse(Console.ReadLine());

            Console.WriteLine("enter your name");

            name1 = Console.ReadLine();

            // object creation

            Program p1 = new Program();

            p1.input(roll1,name1);

            Console.ReadKey();

 

        }

    }

}

Imp

What is named parameters:

In this type of parameters all parameters is used to pass all data values with parameter name

Ex. using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

 

namespace parameters

{

    class Program

    {

        void input(int roll , string name)

        {

            Console.WriteLine(roll);

            Console.WriteLine(name);

        }

        static void Main(string[] args)

        {

            Program r1 = new Program();

            r1.input(name:"raju",roll:243);

            Console.ReadKey();

        }

    }

}

Task 1 :- convert the named parameters into userinput.0

Task2:- create students grade system(js wala)

Into C# function with named parameters.
