2 Array questions
1 Is there anyway to automatically get slices of arrays?
For example, from the array {1 2 3 4 5 6} is there any quick way of getting say elements 2-4 in a new array {2 3 4}?
2 Dynamic array size. I need an array which size is determined by argv first thing in the function. Do I need to start defining structures and pointers or is there a quicker way?
Thanks a lot,

If you're up for a read, this is a good intro into pointers and arrays.
>>any quick way of getting say elements 2-4 in a new array
memcpy() if the elements are contiguous. Or simple direct assignment for each element you want to copy.
>>I need an array which size is determined by argv first thing in the function
malloc() an array then.
This will get you memory for 10 ints
#include <stdlib.h>
int *myarray;
myarray = malloc(10 * sizeof(*myarray));
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Thanks
That was quick and really useful.
Best,
