malloc() allocates 1 unit(datatype) of memory each time it
is called so to allocate memory for a file read char by
char allocating memory each time for a char till EOF.
calloc allocates sizeof(datatype) bytes to the no of
elements in the file, where by the user can specify the
file size as the second arguement.
char *malloc(sizeof(datatype) )
char *calloc(sizeof(datatype), num of elements)
calloc() is more efficient as memory is allocated in 1
cycle so fewer clock cycles, more faster executiop.

Answer / ananth kumar

malloc
Holds 1 argument data type
allocates memory byte equivalent to data type
not init alloted memory

Calloc
Holds 2 arguments, data type and number of datas (n)
allocates memory block equivalent to n * data type
clears alloted memory with 0

Answer / shruti

malloc will only allocate space in the memory..

calloc will allocate space in the memory as well as
initialise it to a particular value.

Answer / prakashdasari

malloc () for allocating the single block of memory
calloc () for allocating multiple blocks of memory
the values assigned are garbage in case of malloc() and
proper values (zeros) are assigned in case of calloc().

Answer / abhishek pathak mnnit

1- malloc() takes one argument while calloc takes 2 argument.
2- default value of malloc is garvage while calloc is 0;
3- malloc allocate memory in contiguous form while calloc
allocate memory in contiguous form if not avilable the takes
diffrent place.

Answer / arshad

1.
calloc function takes two argument while malloc takes only 1
2.
by default memory allocated by malloc contains garbage values
whereas that allocated by calloc contains all zero.

Answer / vini sharma

Answer / madan gopal singh

malloc() is a one argument function while calloc() is two
argument function
malloc() take garbage value at initial time while calloc()
take null values at initial time

Answer / smitha

Malloc:
1. Takes only 1 argument- the size of the memory block to
be allocated.
2. Allocates memory as a single contiguous block.
3. Will fail if a single contiguous memory block of
required size is not available.

Calloc:
1. Takes two arguments - the number of memory blocks needed
and the size of each memory block.
2. It may or may not allocate a single contiguous block,
thus will not fail if a single contiguous memory block
of required size is not available.
3. Initialises the memory blocks to 0.
