C/ C++/ OOPs Questions for Infosys Technical Interview

1) What is the difference between method overloading and method overriding?

Answer:

  • Method overloading means methods are having the same name, but they differ either in the number of arguments or in the type of arguments. It is done during compile time, so it is known as compile-time polymorphism.
  • Method overriding means the ability to define subclass and super-class methods with the same name as well as the same method signatures, here the subclass method will override the super-class method. It is performed during run time, so it is known as run-time polymorphism

2) Explain pointers in C++

Answer:

A variable that has the address of another variable of the same data type can be called a pointer. Pointers can be generated for any data type or for user-defined data types such as class, configuration. It allows variable passing by references using the address. For example:

Syntax:

int x = 25;
int *ptr = &x;
cout << ptr;

  • Here, ptr will store the address of x. That means the address of x is the ptr value
  • Using *ptr, we can obtain the value stored in the address referenced by ptr(i.e., 25). *ptr is known as dereference operator

Example: Uses of pointers

  1. To point a variable present inside the memory
  2. To store addresses of dynamically allocated memory blocks

3)What is the difference between reference and pointer?

Answer:

Pointer stores the address of a variable, but the reference is just a copy of a variable with a different name. References have to be initialized, whereas the pointer need not be. To initialize pointer, we use the dereference operator,

int a;
int *ptr = &a;
// We use the & reference operator to initialize the reference variable.
int a = 20;
int &ref = a;

In the above, while ptr will store the address of a, ref will store the value of a (20). Learn more about references and pointers through this detailed article.

4) What are Structs and how are they different from Classes?

Struct is a customized data type that contains other data types.

i.e., Syntax 

struct Student {
int rollNumber;
char section;
void getName();
};

Note: A class can be inherited but structs cannot.

Members of a class are private by default, to make a variable public, we need to add the public modifier. In a struct, by default members are public and if we need any private members, we have to use a modifier.

5)What is the difference between array and pointer?

 Answer:

  1. An array is the group of similar elements having the same data type, whereas the pointer is a variable pointing to some data type in the memory
  2. Arrays can only contain the elements of a similar data type whereas the pointer variable is used to point to any data type variable

6)Write output of the program?

int i=10;
printf(“%d%d%d”,i,++i,i++);

 Answer: 10 12 12

7) What is inheritance? Name its types ?

Answer:

  1. Inheritance is one of the important concepts of OOPs languages. With inheritance, we can apply the properties of one class to another class.
  2. The concept of inheritance increases the code reusability of the programming language

8)What is the difference and similarity between C and C++?

  • C and C++ both use the same syntax. C++ is the extension of the C language.
  • C and C++ both have same compilers.
  • C++ language consists of classes and objects whereas there are no classes and objects available in the C language.
  • C++ is an OOP based programming whereas C is not OOPS based programming language.

9)What are the different modulation techniques?

  • The two types of modulation techniques are an analog and digital modulation.
  • Further analog modulation is subdivided into amplitude, frequency and phase modulation.

10) Write the program in C language to swap two numbers without using a third variable?

#include<Stdio.h>

#include<conio.h>

void main()

{

int i,j;

printf(“Enter the value of i: \n”);

scanf(“%d”,&i);

printf(“Enter the value of j: \n”);

scanf(“%d”,&j);

printf(“Value of i before swap:%d \n”,i);

printf(“Value of j before swap:%d \n”,j);

i=i+j;

j=i-j;

i=i-j;

printf(“Value of i after swap:%d \n”,i);

printf(“Value of j after swap:%d \n”,j);

 

}

What is the difference between a white box, black box, and gray box testing?

White Box Testing Black Box Testing Gray Box Testing
Internal programming fully known. Internal programming is not known. Internal programming is partially known.
Tester knows the internal working of the application. The knowledge of the internal working of the application is not required. Internal working of the application is partially known.
White box testing is also known as glass, open box, clear box, structural testing, or code-based testing. Black box testing is also known as a closed box, data-driven, and functional testing. Gray box testing is also known as translucent testing.
Performed by tester and developers. Performed by the end user and also by tester and developers. Performed by the end user and also by tester and developers.
The tester can design test data. Testing is based on external expectation. By high-level database diagrams and data flow diagrams.

Difference between ‘Macro’ and ‘ordinary’ definition?

  • Macro takes parameters whereas the ordinary definition does not.
  • Based on the parameter values to macro, it can result in different value at runtime. Ordinary definition value remains same at all place at runtime.
  • Macro can be used for conditional operations whereas the definition cannot.
  • Using macro one can achieve inline functionality in C, i.e., a macro can be a function performing simple operations. This is not possible using definitions.

Explain about Agile mode?

  1. Agile is a software development model that has an iterative approach for software development that helps teams to deliver value to their customers faster, with greater quality, with lesser errors, greater ability to respond to change
  2. An agile team delivers a product in small increments instead of a “big bang” launch. Requirements, plans, and result evaluation is continuously done, so teams have a natural mechanism for a quick response to change

DBMS Questions for Infosys Technical Interview

Differentiate between Char and Varchar in DBMS?

  1. Char and Varchar both are the datatypes in DBMS.
  2. Char and varchar both datatypes are used to store characters up to 8000.
  3. The only point of difference between the Char and Varchar is Char fixed length string datatype whereas Varchar, as the name suggests, is a variable length character storing data type.

For example:

char(7) will take 7 bytes of memory to store the string, and it also includes space. Whereas varchar will take variable space, which means that it will only take that much of space as the actual data entered as the data of varchar data type.

What is the left outer join and the right outer join in SQL?

It returns an entire set of records from the left table along with the matched records from the right table

Why indexing in SQL is useful?

  •  A SQL index is a quick lookup table that helps to find records that are frequently searched by a user.
  • An index is fast, small, and optimized for quick look-ups.
  • It is useful for establishing a connection between the relational tables, searching large tables, and fast retrieval of data from a database

Do you know about the different level of languages?

  • Low-level Language– Language which is understandable by machine is often known as machine language (binary language). It is challenging to read and doing code in this language by humans directly.
  • Assembly level language– Some mnemonics are used which reduce the complexity of the program.
  • Middle-level Language– This language is not so tricky as the assembly language, but it still requires the knowledge of computer hardware which makes it little difficult to program. For Example C and C++ programming languages.
  • High-level language– Its right to say, this level of the programming language is the highest level of the programming language in the technology. These types of programming languages do not require the knowledge of the hardware. This level of the programming language is elementary to learn by the humans. For Example Java, PHP, Perl, Python, etc.

What do you mean by Object-Relational DBMS?

The object-relational database (ORD) is a database management system (DBMS) that are composed of both an object-oriented database (OODBMS) and a relational database (RDBMS). ORD supports the essential components of an object-oriented database model in its schemas and the query language used, such as inheritance, classes, and objects. An object-relational database is also known as an object-relational database management systems (ORDBMS).

List different advantages of DBMS?
