9. What is Memory management in C in Wipro?
The C programming language manages memory statically, automatically, or dynamically.
Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program
Automatic-duration variables are allocated on the stack and come and go as functions are called and return.
For static-duration and automatic-duration variables, the size of the allocation is required to be compile-time constant.
Dynamic memory allocation in which memory is more explicitly (but more flexibly) managed, typically, by allocating it from the heap, an area of memory structured for this purpose.
In C, the library function malloc is used to allocate a block of memory on the heap. The program accesses this block of memory via a pointer that malloc returns. When the memory is no longer needed, the pointer is passed to free which deallocates the memory so that it can be used for other purposes.
10. What is Functionality of Operating System in Wipro?
An operating system (OS) is a set of software that manages computer hardware resources and provides common services for computer programs.
To act as interface between hardware and users, an operating system must be able perform the following functions:
1. Enabling start-up application programs. Thus, the operating system must have:
✰ A text editor
✰ A translator
✰ An editor of links
11. Explain the use of IP address in Wipro?
An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.An IP address serves two principal functions: host or network interface identification and location addressing.
12. Can you please explain the difference between unique and primary key constraints?
A UNIQUE constraint is similar to PRIMARY key, but you can have more than one UNIQUE constraint per table. Contrary to PRIMARY key UNIQUE constraints can accept NULL but just once. If the constraint is defined in a combination of fields, then every field can accept NULL and can have some values on them, as long as the combination values is unique.
13. Explain the steps involved in designing in Wipro?
Project plan, Requirements, Design, Coding, Testing, Re-coding and design, Development, Maintenance.
14. Can you please explain the difference between interface and multiple interface?
Both an abstract class and an interface are specific types of computer objects that allow a programmer to loosely define one type of object as if it were another type, while retaining all of the object's original properties. While multiple different computer languages use one or both of these concepts, Java is the most well-known. Abstract classes and interfaces have a variety of similarities, but also incorporate significant differences in structure, syntax, and usage.
15. How to delete Duplicate row in table of Wipro?
SQL> delete from table_name where rowid not in (select max(rowid) from table group by duplicate_values_field_name).
16. When do we use SQL Profiler in Wipro?
SQL Profiler utility allows us to basically track connections to the SQL Server and also determine activities such as which SQL Scripts are running, failed jobs etc..
17. What is Active objects in Wipro?
Active objects are one which instigate an interaction which owns a thread and they are responsible for handling control to other objects. In simple words it can be referred as client.
18. Explain Program counter in Wipro?
Program counter holds the address of either the first byte of the next instruction to be fetched for execution or the address of the next byte of a multi byte instruction, which has not been completely fetched. In both the cases it gets incremented automatically one by one as the instruction bytes get fetched. Also Program register keeps the address of the next instruction.
19. Give an example of Stored Procedure?
CREATE procedure - is a stored procedure, which is a saved collection of Transact-SQL statements that can take and return user-supplied parameters.
20. What are the benefits of Stored Procedures in Wipro?
❅ Reduced client/server traffic
❅ Efficient reuse of code and programming abstraction
❅ Enhanced security controls
21. What is XML case-sensitive?
XML is case sensitive when uppercase and lowercase characters are treated differently.
Element type names, Attribute names, Attribute values, All general and parameter entity names, and data content (text), are case-sensitive.
22. Explain Null object in Wipro?
It is an object of some class whose purpose is to indicate that a real object of that class does not exist. One common use for a null object is a return value from a member function that is supposed to return an object with some specified properties but cannot find such an object.
23. Explain the property of class in Wipro?
A property is a member that provides access to an attribute of an object or a class. Examples of properties include the length of a string, the size of a font, the caption of a window, the name of a customer, and so on.
24. Can you please explain the difference between static and dynamic modeling?
Static modeling is used to specify structure of the objects that exist in the problem domain. These are expressed using class, object and USECASE diagrams. But Dynamic modeling refers representing the object interactions during runtime. It is represented by sequence, activity, collaboration and statechart diagrams.
25. Tell me does a class inherit the constructors of its super class?
A class does not inherit constructors from any of its super classes.
