second day of c#
using System;
using
System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace commonprogram
{
class Program
{
static void Main(string[] args)
{
int age;
Console.WriteLine("Enter Your
Age");
age=int.Parse(Console.ReadLine());
if (age >= 18)
{
Console.WriteLine("you can
vote");
}
else
{
Console.WriteLine("you
cant vote");
}
Console.ReadKey();
}
}
}
Task
– convert all old assignment into c#.
All
marks>40 then calculate total and display grade (js).
Example
for while loop
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace looping
{
class Program
{
static void Main(string[] args)
{
int i = 1;
while (i < 10)
{
Console.WriteLine(i);
i = i + 1;
}
Console.ReadKey();
}
}
}
#Function:-
It
is a small jobs programs.
#function
separator= ()
#
how to create a function in C#
Syntax:-
Type function name()
{
}
By
default all function is to be created void keywords.
Ex.
Void
display()
{
}
#
In C# all function is created before the main body.
·
To
access any types of function in c# we need to use object.
·
Object
is to be created inside the main body.
·
Syntax-
Classname objname=new
classname();
New is a keyword which means
that it is memory allocation operators.
# how to access function
·
Aceess
function using object
·
Syntax-
Objname.functionname();
;- this are called function
calling operators
Ex for function-
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Text;
using
System.Threading.Tasks;
namespace
function
{
class Program
{ //create a function
void display()
{
Console.WriteLine("welcome"); }
static void Main(string[] args)
{
//create a object
Program p1 = new Program();
//access function
p1.display();
Console.ReadKey();
}
}
}
# all the input are created
inside the main body.
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Text;
using
System.Threading.Tasks;
namespace
function
{
class Program
{ //create a function
void display(int a) // a is called
receiver parameter
{ Console.WriteLine(a); }
static void Main(string[] args)
{
//create a object
Program p1 = new Program();
int n;
Console.WriteLine("enter any
no.");
n = int.Parse(Console.ReadLine());
//access function
p1.display(n);
Console.ReadKey();
}
}
}
