Infosys Technical Interview Questions for Freshers
In this section, we have arranged the Infosys Technical Interview Questions And Answers. And we suggest you to refer the whole of this section and in turn you will get to have an idea of what type of technical questions will be asked in the Infosys Technical Interview.
C/ C++/ OOPs Questions for Infosys Technical Interview
- What is the difference between method overloading and method overriding?
A. 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++
A. A variable that holds the address of another variable of the same data type can be called a pointer. Pointers can be created for any data type or user-defined datatypes like class, structure, etc. It allows variable passing by references using the address. For example:
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.
Uses of pointers:
- To point a variable present inside the memory
- To store addresses of dynamically allocated memory blocks
3. Write a C++ program to check whether a number is palindrome or not.
/* A palindrome number is a number that remains same after reversing the digits. */
#include<iostream.h>
#include<conio.h>
void main()
{
int num, n, rem, rev=0;
clrscr();
cout<<“Enter a number:”;
cin>>num;
n=num; //Used for comparision after reversal of a number
while(num>0)
{
/* In this block, we retrieve each digit from a given number and will get the reversed number at the end stored at rev variable. */
rem=num%10;
rev=(rev*10)+rem;
num=num/10;
}
if(n==rev) //Comparing given number with reversed number
cout<<n<<” is a palindrome.”;
else
cout<<n<<” is not a palindrome.”;
getch();
}
4. What are Structs and how are they different from Classes?
A. Struct is a customized data type that contains other data types.
For example,
struct Student {
int rollNumber;
char section;
void getName();
};
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.
A class can be inherited but structs cannot.
5. What is the difference between reference and pointer?
A. 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.
6. Give examples of data structures in C++.
A. There are two types of data structures in C++, linear and nonlinear.
- Linear – data elements are stored in sequence. Example, stack, queue, and linked list
- Non-linear – tree and graph that are not stored in a sequential manner
7. What is inheritance? Name its types.
A. Inheritance is one of the important concepts of OOPs languages. With inheritance, we can apply the properties of one class to another class. The concept of inheritance increases the code reusability of the programming language.
Various types of inheritance are:
- Single inheritance
- Multi-level inheritance
- Hierarchical inheritance
- Multiple inheritances
- Hybrid inheritance
- Multipath inheritance
8. What are tokens in C++?
A. Tokens are the smallest elements in C++ that make more sense to a compiler. Identifiers, keywords, literals, operators, punctuations, and other separators are examples of tokens.
9. What is the difference between array and pointer?
A. 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. Arrays can only contain the elements of a similar data type whereas the pointer variable is used to point to any data type variable.
10. Write output of the program?
int i=10;
printf(“%d%d%d”,i,++i,i++);
A. 10 12 12

DBMS Questions for Infosys Technical Interview

Char and Varchar both are the datatypes in DBMS. Char and varchar both datatypes are used to store characters up to 8000. 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.
4. 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).

- Working software is produced only at the end of the life cycle

- Not suitable for complex as well as object-oriented projects
- Difficult to measure progress within each stage
- It is difficult to identify any business or technological bottleneck or challenges early because integration is done at the end
