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

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

In this article, we will explore how to interface an EEPROM with an 8051 microcontroller using the I2C protocol. In real-world applications, microcontrollers often come with a limited amount of internal memory. This limitation can become a significant bottleneck during project development, especially when persistent data storage is required. To overcome this, microcontrollers typically offer

In this blog post, we will explore the I2C (Inter-Integrated Circuit) communication protocol in detail. You will learn how it works, including its hardware configuration, frame structure, and data transfer mechanism between devices. We will also explore why I2C is a preferred choice for chip-to-chip communication. We will also cover commonly used terms in I2C
