A pointer to function in C is one of the most important pointer tools which is often ignored and misunderstood by the people. Generally, people face the problem with function pointer due to an improper declaration, assignment and dereferencing the function pointer. Misunderstanding of the fundamental concept of function pointers can create issues in the […]

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 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

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
