#include<conio.h> #include<stdio.h> void main() { int length,breadth,area_of_rectangle; clrscr(); printf("Enter the Length="); scanf("%d",&length); printf("Enter the Breadth="); scanf("%d",&breadth); area_of_rectangle=length*breadth; printf("Area of rectnagle is=%d",area_of_rectangle); getch(); }

Write a Program to calculate area of a circle

#include<conio.h> #include<stdio.h> void main() { double radius,area_of_circle; clrscr(); printf("Enter the radius="); scanf("%lf",&radius); area_of_circle=3.14*radius*radius; printf("Area of Circle is=%lf",area_of_circle); getch(); }

If a five-digit number is input through the keyboard,write a program to reverse the number?

/*Reverse a Number*/ #include<stdio.h> #include<conio.h> void main() { int number,reverse_number; clrscr(); printf("Enter the Number you want to reverse:"); scanf("%d",&number); /*we use while loop and '%' to seprate a number*/ printf("Reverse number is:"); while(number>0) { reverse_number=number%10; number=number/10;//update number printf("%d",reverse_number); } getch(); }

If a five-digit number is input through the keyboard ,write a program to calculate the sum of its digit?

/*Sum of Digit of a Number*/ #include #include void main() { int number,sum=0; clrscr(); printf("Enter the Number you want to Sum its digit:"); scanf("%d",&number); /*we use while loop and '%' to separate a number*/ printf("Sum of its digit is:"); while(number>0) { sum=sum+(number%10); number=number/10;//update number } printf("%d",sum); getch(); }

Concept of Strong name

strong name is used for unique id for.net assembly. it is used when we need to deploy assembly in Gac(global Assembly cache). How to generate Strong name go to visual studio tools> Visual studio Command Prompt There is command prompt window With C:\program files\visual studio 9.0\Vc\ to create strong name type sn.exe -k "c:\test.snk" C:\program files\visual studio 9.0\Vc\sn.exe -k "c:\test.snk" -k is key value parameter and "c:\test.snk" is location to save file after that press enter nd u get key pair return to "path" For using strong Name in Class library in Visual Studio go to Projects > Class library1 properties. > signing make use a key radio button Checked nd browse Location of test.snk nd use test.snk in your Class Library

Different Methods to Pass Values between Web Forms Cross page posting means to post data from one page to another page.this is an important concept in web development. there are many methods to perform this task.some of Them are following.

How to use a cookie. //Cross Page Posting Using Cookies. HttpCookie samplecookie = new HttpCookie("mycookie"); samplecookie.Value = TextBox1.Text; samplecookie.Expires = DateTime.Now.AddHours(1); Response.Cookies.Add(samplecookie); Response.Redirect("default2.aspx"); ON Second page Retrive value using cookies. Label1.Text = Request.Cookies["mycookie"].Value; Query String this is another way to pass value between pages. in it we have to use a question mark (?) as separator. "&" is use to pass multiple query strings. how to use querystring Response.Redirect("default2.aspx?pass="+TextBox2.Text); Retrieve value using Querystring Label2.Text = Request.QueryString["pass"] Sessions it is server side state management method.this is most secure and most acceptable way of cross page posting how to use session on page. Session["user"] = txtName.Text; on second page string str=Session["user"].ToString();
