Answer / monalisa dhal samanta

malloc() is a allocated 1 unit data type.it is a one argument
function .malloc allocate bytes of memory .
calloc() is a allocated sizeof data type .it is a two
argument .

Answer / priya

malloc() allocates bytes of memory for a single block
whereas calloc() allocates blocks of memory for multiple
blocks

Answer / vijay r15

malloc creates the
single block of gn
size by user. Malloc
takes 1ly 1 arg.

Calloc creates
multiple block of gn
size. It will
initialize the
reserved memory block
to zero. Calloc takes
2 arguments

Answer / dilip k. singh(dks)

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.
sUMMARY:
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 / venkateswarlupanidapu

malloc occupies byte of space in memory location and holds
only one argument of data bytes.
calloc occupies and holds 2 bytes of memory in address
location with arguments databytes,number of data bytes.
calloc occupies in structure of blocks and malloc allocates
in struncture of databytes.

Answer / rinky

malloc use boy as a male condom
calloc use girl as a Female condom

Answer / divya sharma

malloc takes the single argument nd calloc takes two argument
malloc initialize byte of memory while calloc initialize the
block of memory

Answer / md ajij

1.malloc() allocate one block of space in memory , argument
of the malloc is the size of the block.
where as calloc() allocate multiple blocks in the memory
,argument of the malloc() is the size of a block and number
of blocks.

2. malloc() takes garbage value at the initial time where
initial value of calloc() is zero.

Answer / naresh guguloth(iiit,basar)b09

malloc():-
-------
It is used to allocate memory for one variable only.
int*hi=(int*)malloc(sizeof(int));
calloc():-
It is used to allocate memory for any array.
int*bye=(int*)calloc(sizeof(int),10)

Answer / bavithra

malloc() doesnot initialize the allocated memory
calloc() initializes the allocated memory to ZERO

How do we select the big element or any other operation from array which is read dynamically. user need to give the elements only no need to mention the size.
