Difference between malloc and calloc?

Question

What is the difference between doing:

ptr = (char **) malloc (MAXELEMS * sizeof(char *));

or:

ptr = (char **) calloc (MAXEL         


        

Answer 1

The calloc() function that is declared in the header offers a couple of advantages over the malloc() function.

1. It allocates memory as a number of elements of a given size, and
2. It initializes the memory that is allocated so that all bits are zero.
