I am allocating 4 bytes of memory using calloc. Now i need more 4 bytes, So i use realloc. But for newly allocated memory block of 4 bytes i need to initialize the memory to 0

`memset` would be one way - http://man7.org/linux/man-pages/man3/memset.3.html `memset(p+4, 0, 4)` – Support Ukraine Nov 15 '19 at 11:45
C or C++, please pick one. – moooeeeep Nov 15 '19 at 11:47

If `C++` you should not be using `malloc` and friends. – kiran Biradar Nov 15 '19 at 11:52
