c - How to print binary content of bytes pointed by a pointer? -

this question has answer here:

i have pointer returned malloc. points first byte of allocated size. ex:

  void* p=malloc(34);

how print binary values contained in 34 bytes. ?

you want :

int ; void* p=malloc(34);  (i = 0; < 34; i++) {   unsigned char c = ((char*)p)[i] ;   printf ("%02x ", c) ; }

it doesn't print in binary (010011011) in hexadecimal, that's want.

but stated in comments garbage values.

And
