The Microsoft ASP.NET framework includes several options to help you preserve data on both a per-page basis and an application-wide basis. These options can be broadly divided into the following two categories:

We can see the execution path of the page and application using the debug statement. We can access and manipulate trace messages programmatically. We can see the most recent tracing of the data. Tracing can be done with the following 2 types. Page Level: When the trace output is displayed on the page and for the page-level tracing we need to set the property of tracing at the page level.

A cookie can store only string value. Cookies are browser dependent. Cookies are not secure. Cookies can store only a small amount of data.

20. What are the Navigations technique in ASP.NET? Answer: Navigation can cause data loss if it not properly handled. We do have many techniques to transfer data from one page to another but every technique has its own importance and benefits.

A Page theme contains the control skins, style sheets, graphic files, and other resources inside the subfolder of the App_Theme folder in the Solution Explorer window. A page theme is applied to a single page of the web site.

When the Header file is included within double quotes (“ “), complier search first in the working directory for the particular header file. If not found, then it searches the file in the include path. But when the Header file is included within angular braces (<>), the compiler only searches in the working directory for the particular header file.

Some of the data types in C have special characteristics of nature when a developer assigns a value beyond the range of the data type. There will be no compiler error and the value change according to a cyclic order. This is called cyclic nature and char, int, long, int data types have this property. Further float, double and long double data types do not have this property.

Features are as follows: Portability: It is a platform-independent language. Modularity: Possibility to break down large programs into small modules. Flexibility: The possibility of a programmer to control the language. Speed: C comes with support for system programming and hence it compiles and executes with high speed when compared with other high-level languages. Extensibility: Possibility to add new features by the programmer.

If you have defined a pointer to a variable or any memory object, there is no direct reference. But when we declare a variable, it has a direct reference to the value. This is called indirect reference. But when we declare a variable, it has a direct reference to the value.

The function definition in C contains four main sections. return_type function_name(parameter list) { Body of the function } Return Type: Data type of the return value of the function. Function Name: The name of the function and it is important to have a meaningful name that describes the activity of the function. Parameter: The input value for the function that is used to perform the required action. Function Body: Collection of statements that performs the required action.

9. What is a constructor?Answer: A constructor is a class member executed when an instance of the class is created. The constructor has the same name as the class, and it can be overloaded via different signatures. Constructors are used for initialization chores.

14. Questions and Answers on Object-Oriented Concepts?Answer: The section contains questions and answers on polymorphism, structures, enumeration, inheritance, method overloading and method overriding, abstract class and interfaces implementation.

Obviously, there are principles like Encapsulation, Polymorphism, Abstraction, and Inheritance, but these are the consequence and not the generating force behind the OO paradigm in C#.

16. What is a delegate in C?Answer: A delegate in C# is an object that holds the reference to a method. It is like a function pointer in C++.

An array contains zero or more items called elements. An array is an unordered sequence of elements. All the elements in an array are of the same type (unlike fields in a class that can be of different types). The elements of an array accessed using an integer index that always starts from zero. C# supports single-dimensional (vectors), multidimensional and jagged arrays.
