Thread: Allocating memory for array of structures

When you create with malloc(), you can use realloc() to adjust the size of the array, up to the limits of memory.

You can use malloc again to create a bigger array. Move the old array to the new one then free() the old array. There are lots of memory allocation and manipulation function that you can use like realloc and memcpy to achieve this. Try looking them up and decide how you can use them your program.

Tater,

Thanks for the info I will remember that.

He should just use realloc()... it does not destroy data (unless you make it too small) and doesn't require any silly memcpy() tricks at all.
