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

Introduction In the article, we see the interfacing EEPROM with 8051 microcontrollers using the I2C Protocol. In the real world, microcontrollers have a limited amount of memory. Sometimes the limited amount of memory becomes a big issue and creates a roadblock to the development of a project. Each microcontroller provides flexibility to connect an external

In this blog post, you will learn about the I2C protocol, the working of the I2C Communication protocol, hardware bus configuration, and how data is transferred in I2C communication with its uses in chip-to-chip communication. I will also explain the terms which frequently used in the I2C protocol. So, let’s begin the post with an
