Answer Posted / chris_sreekanth
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.
