I don't see what's your problem. If I were you, I'd just check the "I don't know" options.

hi ,aron


why are you discouraging me? i tried to find these answers..but i didnt... thats why i posted here..please help me if u dont mind

If you can't find these answers yourself, you are most probably not suitable for the job. If you are telling that you are just testing your C knowledge, you could start from a beginner's tutorial.

1 is rather straight forward. It's obviously not A or C since they deal with external functions. D is just completely wrong so its obviously B.

If we answer these questions for you and you somehow manage to get this job, how long do you think you'd last there before they figured out you don't know enough about programming to do the job properly?

If these are interview questions for a real job, I'd turn down any offer they make you and run. The chance of you getting a good job at a company that asks these ridiculous questions in an interview are vanishingly small. They'll hire exactly what they deserve: a clueless, useless beginner.

On the other hand, if, as I suspect, these are questions from a programming class assignment, you're encouraged to do your own damn homework. :)

can somone explain to me what is keywords mean please ??
