hi when I do ptr=(int*)malloc(10); Does the memory allocate of 10 bytes are in continuous memory area . Does malloc allocates memory conitinous
Yes to both, although this is not good use of malloc. It allocates 10 bytes, but you should allocate N*sizeof(int) instead, where N is how many ints you want. If ints are 4 bytes on your system, this will allocate two and a half of them, of which only the first two are useful.
That is to say it returns a pointer of type void * that is the start in memory of the reserved portion of size number_of_bytes. If memory cannot be allocated a NULL pointer is returned.
