Persistent Technical Interview Questions

Question 1:- Mention the features of the C programming language?


The following are some characteristics of the C programming language:

  • It is both simple and effective.
  • The C programming language is machine-independent.
  • C is a programming language for intermediate programmers.
  • It’s a programming language with a defined structure.
  • It offers a large library of functions.
  • Memory Management in Real-Time.
  • C is a lightning-fast person.
  • In C, we can use pointers.
  • It can be expanded.

Question 2:- In C, what is pointer to pointer?


In C, you can use a pointer to hold the address of another pointer. This type of pointer is known as a double pointer or pointer to pointer. 

  • The first pointer stores the address of a variable. 
  • The second pointer stores the address of the first pointer.

Question 3:- Write a code on Radix sort.

Question 4:- What are the different types of data structures?


The types of data structures are as follows:

List: A Lists are collections of related objects that are linked to the previous or subsequent data elements.

Arrays: Arrays are collections of values that have the same value.

Records: Records are a group of fields that each hold data from a single data type.

Trees: Trees are a type of data structure that arranges information in a hierarchical fashion. This type of data structure follows the addition, deletion, and alteration of data items in a specific order.

Tables: Data is maintained in the form of rows and columns in tables. These are similar to records in that the result of a data change is reflected across the entire table.

Question 5:- Write a program to insert a node in middle of the linked list.

Question 6:- Explain why Python is an interpreted language.


  • The term “interpreted” means that regardless of the programming language you choose for coding, if it is an interpreted language, the machine will execute each line of code line by line. 
  • Python programmes are typically written from source code, with no intermediate compilation stages or processes.

Question 7:- Write a program to search an element in the linked list.

Question 8:- What does Boot.ini do?


Boot.ini displays all of the operating systems installed on the machine and tells you which partitions they are on.

Question 9:- Write a code for finding the Harshad number.

Question 10:- What are Preprocessor Directives?


Preprocessor directives are included at the start of every C program. This is where library files are supplied, which will vary depending on the functions used in the program. The declaration of constants is another application of preprocessor directives. The # symbol denotes a preprocessor directive.

Question 11:- Write a code for Heap Sort.

Question 12:- Write a code for implementing a queue using two stacks.

Question 13:- Explain Priority queue implementation using array.

Question 14:- Explain the insertion in Binary Search Tree.

Question 15:- Explain the deletion in AVL Tree using a program.
