The interview was very tough. Expect to know every basic and tiny detail of 'C' programming. I guess I did not study well, so I did not clear the phone interview.

1. Suppose you have 3 files and a header file that has a static variable declaration in it. You include the header file in the 3 files. What happens? Do you get any errors, or what would happen to the system? From here, the question flow continues.

2. Suppose you have a 32-bit system and a structure with char, int, and double variables. What is the size of the structure? Again, from here, the question continues on memory alignment. How is alignment usually performed? And how do you force the structure to have the exact size, removing alignment?

3. A program to find little and big endian (yes, it was only a phone interview). Well, this is just a one-line expression anyway.
