Answer / namita

1-memory allocated by malloc contains garbage value.But
memory allocated by calloc is initialised to zero.

2-malloc takes only one argument which indicates the size
to be allocated.But calloc takes two arguments.First
argument indicates the number of blocks to be allocated
where as the second argument indicates the size of the
block.

Answer / vara

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.

Answer / bijaya

1)malloc() function does not initialize the memory which it
allocates thats why it takes the garbage value.but calloc()
function initializes the allocated memory to zero thats why
it cant take any garbage value.

2)malloc() function takes single arg.that is the variabe
which is used to indicate the memory size to be
allocated.calloc() function takes two args-i) variable which
indicates the number of memory blocks.ii)variable which
indicates the size of each blocks.
