In this article, we will see how to reverse a linked list in C. For Example, Input : 10->20->30->NULL Output : 30->20->10->NULL   We can reverse the linked list using two approaches. Iterative method Recursive method Iterative method This is the simplest way to reverse  linked list, in which we iterate a loop throughout the linked list

In my previous article, I have discussed the introduction of linked list and linked list insertion. In this article, we will see how to delete a node from the existing linked list. Delete a Node: There are three ways to delete a node from the linked list. It depends on the user requirements. Delete a

In my previous article, I explained the basic concepts of a linked list along with its advantages and disadvantages. In this article, I will show you how to insert a new node into an existing linked list. Earlier, I shared an example where I created a linked list with four nodes. While that example was

A linked list in C is an example of a linear data structure that stores data dynamically using structures and pointers. It allows data to be stored at runtime by dynamically creating new memory locations. Unlike arrays, linked lists do not require a contiguous block of memory. Instead, nodes are connected using pointers. In simpler

In the C function pointer is used to resolve the run time-binding. A function pointer is a pointer that stores the address of the function and invokes the function whenever required. I have already written an article that explains how is the function pointer work in C programming. If you are the then it is

We can find the largest and second largest number of an integers array using the c language. This question is also important and asks by the interviewer in an interview. Let’s take an example, suppose there are an integer array iaData of 5 integers. int iaData[5] = {3, 5, 123, 6, 1}; Here the largest

We can find the smallest and second smallest element of an integers array using the c language. This question is also important and asks by the interviewer in an interview. Let’s take an example, suppose there are an integer array iaData of 5 integers. int iaData[5] = {3, 5, 123, 6, 1}; Here the smallest

In this article, I am writing a c code to generate the map of INDIA. This program is an example of obfuscated code in C language. Here we will take an encoded long string. The long string is simply a binary sequence of characters. Here string is a run-length encoding of the map of India.

In the interview generally, Interviewer asked the question to reverse a string without the using the c library function or maybe they can mention more condition, it totally depends on the interviewer. In this article, I will discuss several techniques to reverse a string. I hope you guys like it. Here I am assuming you

In the interview generally, bit reversal is the common question for the interviewer. There are several methods to reverse the bits of an integer. If you have good knowledge of unary operators then bit reversal is a very simple question for you otherwise, it can be difficult. So it is my personal advice before looking
