If you have an array can you allocate it to a certain amount then if the user fills up the array can you use malloc to adjust the array to add more elements if needed? Thanks for any replies.

Yes, in fact, there's a function similar to malloc that does just that. Look up the function realloc(). It's one of the three allocation functions in C.

I would have detailed it in my post, but my copy of K&R isn't on me as it should be and I don't remember the exact definition.

fyi!

you need to include stdlib.h
and the ptype is

void *realloc(void *ptr, size_t size);

change the size of mem pointed to by ptr

there will be no effect if there is not enough availabe memory
