Answer 1

You seem to be trying to run MS-DOS / Turbo-C code on Linux?

There's no struct time and gettime() function in the Unix C library, you're probably looking for struct tm and localtime() instead, see e.g.:

If you are on ubuntu, you can just do:

srand(time(NULL));

You don't need your own timer() function. If you need more fine resolution than 1 second, look into gettimeofday.
