Hi,

I would be thankful if you could provide me the solution to the following questions in C:

1. Given 2 files, f1 and f2 with thousands of name each. Find the common names in the two files. Extend this to 3 files.

2. Algorithm to count most user viewed pages.

3. Code to find dot and cross product

4. Write a function that accepts a function pointer and check the procId of the calling process. Check if the process was alive at a specific interval. If yes, then invoke the function (pointed to by the function pointer) else return. Write another function that would take a request from the process to stop the first function

5. You have 50000 html files, some of which contain phone numbers. How would you create a list of all the files which contain phone numbers?

6. Write C code for 'tr' program.
C:\> tr abc xyz <file name>
replaces all occurrences of a by x, b by y and c by z in <file name>

7. Given a sentence, find if a specific word occurs in it.

8. Write the data structure for jigsaw puzzle. Assume that there is some method which can tell if 2 pieces fit together. How would you solve the puzzle, minimizing the number of times the function is called?

Is this your interview questions, that you are supposed to answer, YOUR own answer?

If these are your interview questions, you really do need to be able to answer them yourself... several of these are fairly trivial problems, with only some efficiency issues to make them interesting. If, for example, you can't conceptualize a solution for 7 (a simple recursive substring match would do it... maybe 10 lines of code), you don't need to be applying for the programming job.
