There are two differences.
1) is the number of arguments. Malloc() takes a single
argument (memory required in bytes), while calloc() needs
two arguments (number of variables to allocate memory, size
in bytes of a single variable).
2)malloc() does not initialize the memory allocated, while
calloc() initializes the allocated memory to ZERO.

Differentiate between new and malloc(), delete and free() ?
