C programming language is needed for both Computer Science & non Computer Science students. During interviews any company dealing with software development will expect the candidate to have sound knowledge of C. In order to clear the interviews it is necessary to have a strong concept. The questions discussed here are conceptual and important for coding exams as well as technical interviews.

There is belief among some students that C is obsolete. With all the new languages and technologies learning C in-depth is not really necessary. Nothing could be further from the truth. C is firmly tied in with the fundamentals of computer science, and is very intimate with the hardware. It is thus popular for:

a) Embedded system

b) Writing programs where performance is important.

Learning C will force a student to learn things that other languages do not. They can learn Java with little or no understanding of how a computer works under the hood, for example, but C will force them to learn quite a lot of stuff outside the language if they do it right.

Ruby, Python, or JavaScript operate inside of a virtual machine, and therefore, the semantics of the virtual machine are what actually matters. the whole idea of a virtual machine is to provide portability. The goal is to only require knowledge of whatâ??s portable, rather than rely on the details of the hardware that the VM is running on.

C not only operates at hardware level but also operates inside of a virtual machine.

After going through the problems in this course the students will develop an in-depth knowledge of C.
