C is interviewer’s favorite language. If you have good command on C language you can get through Technical Interview easily. Most of the interviewers ask basic questions in C. Some times they may ask you to write small programs like reversal of a string, determining whether the given number is a palindrome or not and finding factorial of a given number using recursion etc. You should be able to write these programs quickly.

Most favorite question for interviewers is interchanging two variables with out using the third variable. Another favorite topic for interviewers is Pointers. Please go through pointers once before going to the interview.

Many interviewers look for logic in your program rather than syntax. Once you write the program you should be able to explain the logic to the interviewer with the help of flow-chart or algorithm. If there are more than one logic for a single program, choose the logic that is simple and easy to understand at the same time it should efficient one.

Introduction to C Language
A programming language is designed to help in processing of certain data and to provide useful information to the user. There are lots of programming languages today that satisfy different needs of the user. For example: C, C++, Java, SQL, HTML, JavaScript etc. It helps to write a sequence of instructions that the computer can understand.

Actually, computer understands only machine level instructions i.e. 1 and 0. But it is really impossible to write a program using these binary digits. So, high level languages came into existence where the programmer can write the instructions using English like statements. And the Compiler takes the responsibility to convert a high level program into machine level instructions.

C language came into existence in 1972 as a high level language. It was developed by Dennis Ritchie at Bell Laboratories. It is one of the most popular programming languages today. C can run under a number of operating systems including MS-DOS. It is well suited for structured programming.

It is a robust language with number of functions and operators to handle any complex program. Both system software and business packages can be developed using it. C is highly portable i.e. C program written for one computer can be run on another without modification.
