Clearing all bits in an unsigned char

I am trying to clear all the individual bits in an unsigned char and i assigned the char to zero.I am not sure if thats the right way

That is one way (though you probably meant "I assigned zero to the char").

calloc is originally from C but you can use it in C++ too.

It puts zeros in the allocated memory chunk

calloc is a wrong solution here both in C and C++ since its primary purpose is dynamic memory allocation. You were probably thinking of memset instead.

In C++, there is std::fill instead of memset.
