Top 10 C Coding Interview Questions and Answer (2024)

C is a general-purpose programming language that was created in the early 1970s by Dennis Ritchie at Bell Labs. It has since become one of the most widely used programming languages and has influenced many other languages. C Coding Interview Questions are generally asked in interview.

Write a C program to swap two bits in a bytes.

In the realm of programming, especially in languages like C, bit manipulation is a powerful tool that allows developers to perform various operations at the lowest level of data representation. One interesting task within this domain is swapping two bits within a byte. In this blog, we'll delve into a simple yet insightful C program that accomplishes this bit-swapping magic.

Write a C program to find whether a given number is prime or not

given number is prime or not? A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In simpler terms, a prime number is only divisible by 1 and itself. For example, 2, 3, 5, 7, and 11 are prime numbers, while 4, 6, 8, and 9 are not, as they can be divided evenly by numbers other than 1 and themselves

Understanding AUTOSAR Architecture: A Guide to Automotive Software Integration

AUTOSAR was initiated in 2003 as a collaborative effort between major automotive manufacturers and suppliers. The goal was to establish a common framework for automotive software development, aiming to address the growing complexity of vehicle electronics. Over the years, AUTOSAR has evolved to meet the increasing demands of the automotive industry. Today, it has become a de facto standard, shaping the way vehicle software is developed and integrated.
