TATA ELXSI Interview Questions and Answers

1. What in C is a pointer?

A variable and a pointer are similar, but a variable saves a value, whereas a pointer stores the address to a location in memory. To put it another way, we can say that a pointer is used to refer to a certain address in memory.

In other words, a pointer is used to refer to a particular position in the memory. When we use a pointer to store the address in memory, we can then use dereferencing techniques to get the value from the location that the pointer has saved.

Syntax of a pointer in C: The declaration of a pointer is crucial since you define the pointer’s capabilities at that time. The names and data types (pre-defined or user-defined) of each pointer are followed by an asterisk (*). Asterisk is a unary operator.

2. Explain a NULL pointer.

According to the C standard, a null pointer constant is an integer constant expression with the value 0, or such an expression is converted to type void *. When a null pointer constant is converted to a pointer type, the resultant pointer is called a null pointer.

3. In C, what is the use of the pointer?

There are several ways to use pointers in C, but here are a few that you should be familiar with.

• In dynamic memory allocation, pointers are mostly used. We can access the memory used up by a program’s execution using the memory management function.
• The elements of the array can be accessed via pointers. C Pointers allow us to access the memory location.
• When performing “call by reference,” pointers are used. where we can pass a function to the address of a variable (function, array, etc.).
• For example, linked lists, trees, and other complex data structures use pointers.

4. In C, what is a far pointer?

A far pointer is often a 32-bit pointer that can access memory outside of the current segment. To use this, the compiler creates a segment register to hold the segment address, followed by another register to store the offset inside the current segment.

5. In C, what is a near pointer?

A near pointer is a pointer that is used to store a bit address of up to 16 bits in a 16-bit enabled portion of computer memory. We can only access 64 kb of data at a time due to the limitation

6. What exactly is endianness?

Endianness refers to the order of bytes stored in memory as well as the order of byte transmission over a digital link. Endianness is classified into two types: little endian and big endian, and the order in which data is stored in memory is determined by the endianness.

7. Write a C program to convert from little-endian to big-endian and big to little-endian.

#include stdio.h>
    #include inttypes.h>
    //Function to change one endian to another
    uint32_t ChangeEndianness(uint32_t u32Value)
    {
        uint32_t u32Result = 0;
        u32Result |= (u32Value & 0x000000FF) << 24;
        u32Result |= (u32Value & 0x0000FF00) << 8; u32Result |= (u32Value & 0x00FF0000) >> 8;
        u32Result |= (u32Value & 0xFF000000) >> 24;
        return u32Result;
    }
    int main()
    {
        uint32_t u32CheckData  = 0x11223344;
        uint32_t u32ResultData =0;
    
        //swap the data
        u32ResultData = ChangeEndianness(u32CheckData);
    
        //converted dataz
         printf("0x%x\n",u32ResultData);
        return 0;
    }

8. In an operating system, what inter-Process Communication (IPC)?

Inter process communication

IPC is used for sharing data between many threads in one or more processes or applications. The processes might be functioning on a single computer or several computers linked by a network. It is a collection of programming interfaces that allow a programmer to coordinate operations among several program processes that can run simultaneously in an operating system. This enables software to handle several user requests at the same time.

9. What are various OS (operating system) types?

The following are the most common types of OS (Operating System):

• Batch
• Multitasking/Time Sharing
• Multiprocessing
• Real-Time
• Distributed
• Network
• Mobile

10. What is the callback Function in C?

In the C programming language, a callback is an event-driven function that sends an argument to another function. A function pointer is used to send a reference to “function 1” as an argument to “function 2” in a callback function.

11. What are syntax errors described as?

Syntax errors are mistakes or errors that happen when writing a program. Common examples of syntax mistakes include misspelled or incorrectly cased instructions, an inappropriate number of parameters when calling a method or function, and data type mismatches.

TATA ELXSI Interview Questions for Freshers

1. Describe comments in the context of C++.

Comments are lines of source code that the compiler ignores and are not part of programs. The goal of comments is to inform the programmer about extra information. It provides details on the source code. In C++, comments consist of two types:

Single-line comments: The compiler ignores anything on the line that comes after the commenting character “//” (which is used for commenting).

Multiline comment or block comment: It uses the syntax ” /* ” ” */ ” and the compiler ignores everything in between.

2. What do you know about RTTI?

RTTI

Run-time type information is known as RTTI. At runtime, this mechanism provides information on the data type of an object. It is only available to classes that have at least one virtual function. During the execution of a program, you can identify the type of an object.

3. What is the use of this pointer and the void pointer?

This pointer: The ‘this pointer’ is present in every object’s member functions. It points to the object and can be used to get the object’s data.

Void pointer: A void pointer is a pointer that does not have a data type associated with it. A void pointer may be assigned to any type of pointer, but the reverse is not true unless you use it as follows.

ptr = (char*) str;

4. What exactly is Deadlock?

A deadlock occurs when two or more processes wait for each other to complete and none of them ever do. Consider the following scenario: two trains are approaching each other on the same track, and there is only one track; neither train can move once they are in front of the other. In operating systems, a similar scenario happens when two or more processes hold certain resources and wait for resources held by others.

5. Explain how to boot an operating system.

The term “boot” is a short form of “bootstrap,” which is the name of the program that prompts the operating system upon starting. When you start a computer from the kernel, this is referred to as booting. This is typical when you initially begin. It may also occur when the computer fails and you must boot it into safe mode or reboot it as if it were a new CPU.

6. What are the functions printf() and scanf() used for?

The output will be displayed on the screen using the printf() function.

The scanf() function is used to read formatted data from the keyboard.

7. How can I release a previously allocated block of memory without using free?

The memory will be released if the pointer containing that memory address is passed to realloc with the size parameter set to zero (as in really(ptr, 0)).

8. How can I use a function call before main()?

To call a function, use the pragma startup directive. Pragma starting can be used in this manner:
    #pragma startup fun
    
    void fun()
    {
        printf(“In fun\n”);
    }
    main()
    {
        printf(“In main\n”);
    }

The above program's output will be:

In fun
    In main

9. In Java, what is the final method?

In Java, the final keyword is used to limit the user. The final keyword in Java can be utilized in a variety of ways. The conclusion might be Variable, method, or class. A final variable without a value is known as a blank final variable or an uninitialized final variable. The final keyword can also be used with variables.

10. What exactly does the term “exception” mean?

An exception is a problem that can arise during the normal flow of execution. When anything wails during runtime, a method might throw an exception. If the exception cannot be handled, the execution is terminated before it completes the task.
