What is the difference between "calloc(...)" and "malloc(...)"?

What is  the difference between "calloc(...)" and

 "malloc(...)"?

1. calloc(...) allocates a block of memory for an array of elements of a

certain size. By default the block is initialized to 0. The total number of

memory allocated will be (number_of_elements * size).

malloc(...) takes in only a single argument which is the memory

required in bytes. malloc(...) allocated bytes of memory and not blocks

of memory like calloc(...).

2. malloc(...) allocates memory blocks and returns a void pointer to the

allocated space, or NULL if there is insufficient memory available.

calloc(...) allocates an array in memory with elements initialized to 0

and returns a pointer to the allocated space. calloc(...) calls malloc(...)

in order to use the C++ _set_new_mode function to set the new

handler mode. Blog Author: Vijay Kumar Go to: Java Aptitude, C C++ Topic Explanations
