Interview Questions C is the most popular programming language developed by Dennis Ritchie at the Bell Laboratories in 1972 to develop the UNIX operating systems. It is a general-purpose and procedural programming language. It is faster than the languages like Java and Python. C is very versatile it can be used in both applications and technologies. C is the most used language in top companies such as LinkedIn, Microsoft, Opera, Meta, and NASA because of its performance. To get into these companies and other software companies, you need to practice C programming MCQs. The questions asked in the online test is based on code outputs, error finding, C algorithms and C coding questions. This C Multiple Choice Questions article will cover all the basic to advanced MCQs on C programming language which are selected under the guidance of the masters of C and by getting ideas through the experience of students' recent C programming MCQ Test.
