In c malloc allocate contiguos or non contiguos memory allocation ?

      void *ptr= malloc (20);

      int *iptr= (int *)ptr; //4 byte access  

      char *cptr=(char *)ptr; // Single byte access 

• Malloc allocates contigous block of memory  
• Memory is alocated from heap 
• Memory can be used by typcasting the void pointer returned by the malloc 

malloc/calloc both functions allocate memory in one contigous block

Non Contagious
