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

Previously we have read how to find prime number using C code, here we will learn how to find the all prime number up to n. A prime number is a positive natural number, whose value greater than 1 and it has only two factors 1 and the number itself. Either you can say that

Do you know you can use a function pointer in the structure? I assume your answer is “YES” but however if your answer is “NO”, then it is my recommendation that you should read the article “How to use the structure of function pointer in C?” In this blog post, I will explain the different

A prime number is a positive natural number, whose value greater than 1 and it has only two factors 1 and the number itself. Either you can say that prime numbers only divided by itself and 1. Any positive natural number who is not a prime number is called a composite number. For example, 2,3,5,7,11.. In

The volatile keyword is a qualifier it has a lot of importance in the programming language but problem is that many programmers are not aware of how to use the volatile keyword and when need to qualify a variable from the volatile keyword. Most of the textbooks don’t give importance to this topic either and

Factorial is used in many areas of mathematics but mainly used in permutation and combination. Factorial is the product of the all positive number from 1 to n (user entered number). In simple words, we can say that factorial of n would be 1*2*3*…..*n. Note: There is no factorial exist for the negative number and
