Fun with calloc and malloc
Author
Is calloc(elementNumber, size) the same thing as calling malloc(elementNumber * size)?
I know this works for dynamic arrays in C, but is there a standard C++ equivalent for handling them?
The new and delete operators. You could still use malloc or calloc, but it''d be considered bad practice.

Oh! That's right... I've used them before. I just completely forgot about them. Heh.
Oh, and one more thing: Does free() work with calloc()? Or do I have to use realloc() with a size of 0 to free memory allocated with calloc?

free works with calloc.

Remarks
The free function deallocates a memory block (memblock) that was previously allocated by a call to calloc, malloc, or realloc. The number of freed bytes is equivalent to the number of bytes requested when the block was allocated (or reallocated, in the case of realloc). If memblock is NULL, the pointer is ignored and free immediately returns. Attempting to free an invalid pointer (a pointer to a memory block that was not allocated by calloc, malloc, or realloc) may affect subsequent allocation requests and cause errors.
